CORUM links its name to the world’s most important regatta on an inland lake by becoming Presenting Sponsor of the Bol d’Or Mirabaud, which will commence on June 12. Reaffirming its commitment to sailing, CORUM is continuing its history and expanding its presence in the sailing sponsorship arena.


CORUM is very pleased to be associated with this major event. This partnership is completely consistent with existing partnerships and is in line with the brand’s primary goal which is to create long-term value.

The Bol d’Or has indeed become one of the favorite venues of the Okalys-Corum team who won the regatta twice in the past five years (in 2005 and 2007). It is also to be noted that at the time of these two victories, the skipper alongside Nicolas Grange was Loïck Peyron, CORUM’s new ambassador. With his breathtaking list of accomplishments, the Frenchman, who is regarded as one of the greatest sailors, keeps a unique memory of his past participation in this regatta: « To win the lake’s most popular regatta is quite an achievement. Before I used to follow it from a distance, but in 2005 when we won it for the first time, Nicolas Grange presented us with a small replica of the highly coveted trophy. It still takes pride of place on my desk.»

The Bol d’Or Mirabaud, currently in its 72nd year, is unlike any other regatta in the world. The legendary race is a place where sailing stars are mixed with non-professional sailors, and the event is the pride of the Lake Geneva region and delights sailing enthusiasts.

Organized for the first time in 1939, this large nautical festival has become one of the greatest classics of the international regatta calendar. Each year, nearly six hundred sailboats and champions from all over Europe meet at the starting line, in the company of more than 3,000 participants from all backgrounds, having their passion for sailing in common.

CORUM CEO Antonio Calce said:
« The rebirth of the CORUM brand, which has expressed itself by returning to its roots, has naturally brought us to support the sailing world to which we have always had a strong connection. I am proud to associate CORUM with the historical regatta of the Bol d’Or. Today we build our future in continuity as in 1994, the Corum boat that participated in the 56th edition of the Bol d’Or won the monohull class competition and still holds the record in this category (Bol d’Or Vermeil). We therefore are looking forward to participating in this great adventure of which values cherished by CORUM, such as authenticity and passion, are also the key words of the event. »

This new partnership is strengthening the brand’s ties not only to amazing sailors such as Ben Ainslie and Loïck Peyron but also to prestigious sailing events such as the Grand Prix Corum, which this year will be the final race in the Challenge Julius Baer, taking place on September 17, 18 and 19.

In order to celebrate this partnership, CORUM will launch a limited edition “Admiral’s Cup Chronograph 48 Bol d’Or Mirabaud 2010 “ of 35 pieces. The special edition of the brand’s iconic model famous for its dodecagonal bezel and a dial decorated with nautical pennants, will play with the colors of the regatta which are Blue and Gold. The model will symbolize the partnership by becoming the official replica Watch of the Bol d’Or Mirabaud and one of these limited edition timepieces will be presented to the winning team of the Bol d’Or and the Bol de Vermeil.

Managing Partner and Member of the Executive Committee of Mirabaud, Antonio Palma, added:
« Every year we look forward to the unique event that is the Bol d’Or Mirabaud. At the 72nd regatta, we are pleased to welcome CORUM by our side as presenting sponsor. We anticipate that the future of this collaboration will bring great rewards to all parties during one of the most important sporting events in Geneva. »


The racecourse is as simple as it can get: Genève – Le Bouveret – Genève. There is only one mark on the course, halfway through the race (at Le Bouveret).

The real time winner of the Genève-Le Bouveret-Genève race wins the Bol d’Or Challenge, which is presented each year, however if it is won three times in the previous five years by the same owner, it can be kept by the winner indefinitely. Only three boats have achieved this in over 70 years of the regatta: the Marie-José II owned by Horace Julliard (1961, 1962 and 1963), the Altaïr IX owned by Philippe Stern (1980, 1982 and 1984) and Ernesto Bertarelli’s Alinghi (1997, 2000 and 2001).

The Bol de Vermeil Trophy rewards exclusively the first monohull to cross the finishing line. As for the Bol d’Or Challenge, it has to be won three times in five years to be awarded indefinitely.



Over the past few years, CORUM has undergone a complete transformation that has enabled it to achieve a perfect match between the products and the demands for quality and creativity that are the very foundations of its credibility. Its firmly upscale move is a logical result of the brand’s efforts to recapture its historical standing while significantly reinforcing its horological substance. CORUM’s substantial investments have led to the integration of replica Watchmaking skills, the development of production tools, the enhancement of human resources and the promotion of staff training. The result is a brand once again entirely in tune with its genetic heritage.

Bol d’Or Mirabaud Organization Committee President, Michel Glaus, said:
« As the world’s most important regatta on an inland lake, the Bol d’Or has always been able to count on very prestigious partners. The 2010 regatta will not be an exception as the Bol d’Or Mirabaud is pleased to welcome CORUM as the new “presenting sponsor”, alongside our title sponsor, Mirabaud private bank. We look forward to our future collaboration with this renowned replica Watchmaking company, long known for its strong identification with the world of international sailing.»

While passion, determination and innovation are associated with CORUM’s image today, it is mainly shared values that are at the heart of this partnership. The magnificent adventure will take place June 11-13, 2010.

Positioned as an exclusive brand, CORUM offers high-quality replica Watch collections featuring innovative and distinctive design, and equipped with sophisticated mechanical movements. Its 150 current models, spread between four key pillars – Admiral’s Cup, Romvlvs, Corum Bridges and Artisans – enjoy a legitimacy rooted in the brand history. The full set of collections comprises models at prices ranging from 5,000 to 1 million Swiss francs and giving pride of place to precious metals and horological complications.

In 1960, the first interpretation of the Admiral’s Cup model paved the way for CORUM’s success. This model remains thanks to its history, which is inextricably bound up with major sailing competitions and prestigious sailors, as well as for its inimitable esthetic based on a twelve-sided case and a dial set off by twelve nautical pennants. These are its distinctive and unmistakable identifying characteristics.

Antonio Calce, CEO of Corum, hosting 150 journalists to celebrate the half-century of the Admiral’s Cup and the 30th anniversary of the movement Golden Bridge and share with them the way that Corum has come since its founding 55 years ago.

A landmark event for Corum that celebrates in 2010 the anniversary of two of its main pillars: Admiral’s Cup and Corum Bridges.


With the take-over of the U.S. market in October 2009, the opening of its first boutique in own name on December 25, 2009 in Hong Kong and the reorganization of its market in South America and the Caribbean in early 2010, Corum has reaffirmed its presence around the world and strengthen its strategy of selective distribution.

This is with “Happy Birthday” by the Beatles that the conference began. Major event, the Basel Fair is a unique opportunity to meet during 10 days all our partners and the international press.



2010, an intense year as Antonio Calce, Corum CEO, also confirmed the signature of two new partnerships, one with a new ambassador and the second with a sailing event. Today Corum built partnerships in line with its values and history. If the ambassadors of Corum are distinguished by their sporting qualities, they are also friends of the brand whose human qualities prevail. To top off the press conference, the new website of the brand has been unveiled in a preview. A virtual showcase that takes you to visit the know-how of the brand, to discover our human capital and our history.


In 2010, they are exceptional pieces affirming the creativity and know-how that let Corum be once again among the brands of Haute Horlogerie.

Among the 36 new models launched in 2010, 4 models stands out now among the talking that will set a stone in time. The Golden Bridge Tourbillon with the smallest tourbillon cage escapement in silicium, the Ti-Bridge Tourbillon with a flying tourbillon anchored on a ARCAP bridge (material used in aeronautics) and the Admiral’s Cup Tourbillon Minute Repeater with complications dress a sporty case, the Admiral’s Cup Deep Hull waterproof to 1000 meters with a unidirectional rotating bezel and a helium decompression valve.

Corum goes on with the integration of technical and replica Watchmaking skills, from its engineers to its master replica Watchmakers. Corum is aware of the value of human capital and their unique knowhow and seeks to perpetuate and enhance the historical value of the replica Watch brand. Corum develops in-house movements and to both generate and control production of exclusive movements.

New Hamilton movements

The H-22 is a small second movement and a key to opening up striking dial design possibilities. Hosting its première is the RailRoad Small Second, which uses the facility for the asymmetric positioning of the small second counter at eight o’clock to great aesthetic effect.

The trio of new H-10, H-30 and H-40 Hamilton movements boasts a power reserve of 80 hours. This derives from the refinement of the entire kinematic chain, from the barrel to the escapement. Particularly the suppression of the escapement regulator facilitates optimal reliability and precision, complementing the capacity to store double the power of comparable standard movements. All three movements use traditional materials and their mono-block rotor is distinctively skeletonized with an “H” shape and aviation-inspired cut-outs, a signature of individualization.

Baselworld: OMEGA Master Co-Axial calibres Releases

The staffs and pivots in the new OMEGA Master Co-Axial calibres are made made from a non-magnetic material called Nivagauss and the steel plates found in the Co-Axial movement have been replaced with non-magnetic plates. Further more, the spring of the shock absorber has been crafted from an anamorphous material.

In 2007, OMEGA introduced its revolutionary, state-of-the-industry Co-Axial calibre 8500, featuring technology that redefined the way mechanical replica Watch movements were manufactured in the 21st century. This year, the brand has announced the “evolution of the revolution” with its new Master Co-Axial calibres, marking a dramatic step forward in terms of the robustness and reliability of the brand’s flagship mechanical movement, both in men’s and women’s replica Watches Replica.

best replica watches
Baselworld will open its doors in less than a week and as an appetizer, let me introduce you to three new models by Chopard: the absolute racing piece, the Mille Miglia GTS Power Control, the elegant L.U.C Regulator and for ladies the diamonds and steel Happy Sport 30mm Automatic.

Mille Miglia GTS Power Control

Mille Miglia GTS Power Control

Mille Miglia GTS Power Control

Inspired by the shape of classic cars, the Mille Miglia GTS Power Control is 43 mm, fitted with short, pointed lugs that are carefully tapered to ensure optimal comfort on the wrist, while the sporting nature of these timepieces is enhanced by facetted hands. The direct reference to cars can be further observed on the black dial, the power-reserve indicator with a design that evokes a petrol gauge typical of the 1950s, the black aluminum insert bezel and of course the black rubber strap inspired by the 1960s Dunlop racing tyres.

Chopard has first launched its Mille Miglia racing collection in 1988, born from the fascination for classic cars nurtured by Karl-Friedrich Scheufele, co-president of Chopard. This year they will extend it with the Mille Miglia GTS (for Grand Turismo Sport) collection. It will be composed of a three-hand and date chronometer, a power reserve and a chronograph, sees the introduction of a Chopard movement: for the first time, the chronometer and power-reserve models will be equipped with a Chopard movement from the workshops of Fleurier Ebauches.

The back of the Chopard Mille Miglia GTS Power Control

It is powered by the COSC certified, automatic Chopard 01.08-C calibre, developed, designed and assembled within the workshops of Fleurier Ebauches. Beating at 28,800 vph (4 Hz) it offers 60 hours of power reserve.

L.U.C Regulator

Chopard L.U.C Regulator

Chopard L.U.C Regulator

In their L.U.C Haute Horlogerie collection, Chopard will present a timepiece combining the L.U.C case with a regulator movement. In keeping with the grand tradition of precision clocks, the six indications on the L.U.C Regulator are separated to ensure optimal readability.


The back of the Chopard L.U.C Regulator

The back of the Chopard L.U.C Regulator

Each L.U.C 98.02-L movement of the L.U.C Regulator has successfully undergone the tests conducted by the Swiss Official Chronometer Testing Institute, thereby guaranteeing its chronometric precision. The replica Watch is thus authorised to bear the inscription “Chronometer” on its dial. Moreover, its case and its movement have passed the stern tests performed by the Poinçon de Genève quality hallmark, which certifies the fine technical and aesthetic craftsmanship of the replica Watch, and in particular the high level of finishing on its mechanical parts.

Contrary to almost all available regulators, which place the hours at noon, those of the L.U.C Regulator appear at 3 o’clock. This means they peek out beyond a shirt cuff and are thus legible in all circumstances. The unique nature of the L.U.C Regulator also lies in its other atypical indications. Its dial features exquisite symmetry, with its four cardinal points each occupied by an indication. At noon, the power-reserve indication proudly indicates the autonomy of L.U.C Calibre 98.02-L on a graduated scale. The hours are placed at 3 o’clock, while the small seconds beat steadily at 6 o’clock.

The fourth of these strategically placed items of information is a dual-time display appearing at 9 o’clock. This GMT function is controlled by a corrector-pusher discreetly recessed into the side of the L.U.C Regulator. The date is visible through a window between 4 and 5 o’clock.

The L.U.C Calibre 98.02-L, measuring only 4.9 mm in thickness, delivers an impressive power reserve of 216 hours, equivalent to 9 days.

Happy Sport 30mm Automatic

Chopard Happy Sport 30mm with stainless steel bracelet (Ref. 278573-3002) and the diamond set bezel on alligator strap (Ref. 278573-3003)

Chopard Happy Sport 30mm with stainless steel bracelet (Ref. 278573-3002) and the diamond set bezel on alligator strap (Ref. 278573-3003)

The new Happy Sport 30mm Automatic is available with a polished steel or diamond-set case. Five floating diamonds whirl about its silver-toned dial featuring a spiral guilloché centre pattern. The crown, also made of steel, is set with a blue sapphire, while the steel bracelet or alligator leather strap accentuates the singularly graceful appeal of this model.

In 1993, Caroline Scheufele, Chopard Co-President and Artistic Director, designed a sporty replica Watch based on an original design in an unexpected combination – steel and diamonds. The Happy Sport was born. True to the spirit of Happy Diamonds, these gems dancing freely between two sapphire crystals soon became a symbol of Chopard and feminine replica Watchmaking as a whole. In 2013, Chopard celebrated the 20th anniversary of this replica Watch with the development of a mechanical model – the Happy Sport Medium Automatic – featuring redesigned lines and details.

We look forward to learn more about the new models that Chopard will release this year. In the mean time, keep an eye on

A Comprehensive Guide to the New Rolex Caliber 3255

Rolex Caliber 3255 Cover

Rolex has developed a new methodology and high-technology equipment to test the precision of its Superlative Chronometers with tolerances that are twice as exacting as those for official certification, and under conditions that simulate the wearer’s real-life experience.

Rolex Calibre 3255 - Perpetuelle

Rolex introduces the new Calibre  3255, a new-generation mechanical movement with 14 patents.  Among many noteworthy items, Rolex is quick to point out that the Calibre 3255 sets a new level of chronometric precision with criteria surpassing those of COSC (the Swiss Official Chronometer Testing Institute).  Somewhat analogous to the “Patek Philippe developing its own in-house “Seal”, these exclusive Rolex chronometer tests complement the official COSC certification, to which all Rolex movements continue to be submitted systematically, and are carried out not on the movements alone, but on the assembled Watches Replica Replica after the movements have been cased.

Rolex Caliber 3255 Key Figures - Perpetuelle

Thanks to a new barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3255 extends to three days, which means a Rolex Watch Replica with the Cal 3255 can easily handle some weekend off-wrist time.  The first Watch Replica to receive the new Calibre 3255 is the Oyster Perpetual Day-Date 40, featuring a modernized design with a 40mm case, available in a range of emblematic new dials.

The 3255 incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability.  The oscillator has an optimized blue Parachrom hairspring, which is also up to 10 times more precise than a traditional hairspring in case of shocks. Here is the Day-Date 40 in platinum case, with very attractive, laser-etched blue dial:

Rolex Day-Date 40 images - Perpetuelle


Rolex Caliber 3255 constituent parts - Perpetuelle


The Chronergy escapement of calibre 3255, developed and patented by Rolex, is an optimized version of the Swiss lever escapement. Its energy efficiency has been enhanced while preserving its reliability.  To make it more efficient, Rolex engineers analysed the Swiss lever escapement and isolated the key parameters to be modified. The solution arrived at involved reversing the length ratios between the escape wheel teeth and the pallet stones. While the pallet stones are now only half as thick as before, the contact surfaces of the escape wheel teeth have been doubled.

Rolex Caliber 3255 Chronergy Optimized Escapement - Perpetuelle

Rolex Chronergy Escapement

The oscillator of calibre 3255 is fitted with a blue Parachrom hairspring, patented and manufactured by Rolex in an exclusive alloy of niobium and zirconium. It is insensitive to magnetic fields and temperature variations, and up to 10 times more resilient to shocks  than traditional hairsprings.  You can also see its optimized Breguet overcoil, which enhances the isochronism of the oscillations in any position.   The large balance wheel with variable inertia is fitted with four gold Microstella nuts enabling extremely precise regulating.  Its redesigned geometry and the high-precision machining have enhanced the poise three-fold.

Moreover, the escapement elements are no longer in alignment but are slightly off-set in order to increase the lever effect.  The pallet fork and escape wheel are made in nickel-phosphorus to be insensitive to magnetic interferences. The escape wheel has a cut-out design to make it lighter and reduce its inertia.  Together, these modifications to the geometry have increased the efficiency of the escapement by 15 per cent, contributing to almost half of calibre 3255’s enhanced power reserve.
The oscillator is attached to a new balance staff with exclusive geometry offering added resistance to magnetic interferences. It is fitted on high-performance Paraflex shock absorbers and is held firmly in place by a traversing bridge further reinforcing shock resistance. The balance bridge features an optimized height-adjustment system and new integrated protection for the balance wheel.

Rolex Caliber 3255 Parachrom Hairspring - Perpetuelle


The space inside the barrel was optimized by halving the thickness of its walls. Thereby increasing the movement’s autonomy by more than 10 hours.

Rolex Caliber 3255 High Capacity Barrel - Perpetuelle


The setting interface of calibre 3255 is more ergonomic and user-friendly. The stops marking the positions of the winding crown are distinct and easily sensed. The setting system has been optimized, making for faster day and date adjustment. Time setting is very precise with no play. The calendar can be corrected at any time with no restrictions, thanks to retractable fingers inside the mechanism.

Rolex Caliber 3255 setting mechanism - Perpetuelle


The caliber also uses new reversing wheels in the rotor architecture which provide faster, more efficient bidirectional winding, whatever the wearer’s activity. A new, monobloc, cut-out oscillating weight on a ball bearing improves shock resistance and efficiency.


Rolex Caliber 3255 Accelerated Self Winding - Perpetuelle


The stringent test protocol mentioned in my opening paragraph was designed by Rolex following large-scale statistical studies to determine the actual conditions of daily wear. As a result, the Rolex chronometers equipped with movements tested according to this new methodology demonstrate superlative precision on the wrist.

The Calibre 3255 is equipped with a self-winding module via a new-generation perpetual rotor, for more rapid winding of the new high-capacity mainspring.  The reversing wheel system enables winding in either direction of the weight rotation. This system, with its characteristic red wheels, has been optimized to reinforce its efficiency whatever the activity of the wearer. The now monobloc oscillating weight has been cut-out to absorb shocks. It is fitted on a ball bearing and is held at its centre by a single screw, thereby facilitating assembly.

I’ll close with a personal thought:  I don’t consider myself a Rolex Addict (though I deeply respect and admire the brand), but I am truly excited about this new caliber.
