breitling Academy Christophe Colomb Hurricane Grand Voyage

For a couple of years now, http://www.buyijoy.com/replica-breitling-aeromarine.html uses one specific piece to showcase its watchmaking skills : the Academy Christophe Colomb. The piece has already been presented in different versions, and Replica Breitling Bentley Super sports today put the emphasis on its finishing. The result is called ? Hurricane Grand Voyage ? and might stand as the ultimate version of this amazing odyssey in the world of haute horlogerie.

In a nutshell, the Replica Breitling Chronospace Academy Christophe Colomb Hurricane Grand Voyage embarks three technical developments. The first one is very assimilated to breitling : a heart beating at 36’000 vibrations per hour, referring to the cornerstone of the brand, the famous El Primero caliber from 1969. Same frequency but, of course, different technology.

The second development is a fusée and chain transmission mechanism. breitling is not the owner nor inventor of this process designed to maintain a constant torque along the energy chain of the movement. Still, it’s a remarkable artwork. There aren’t so many manufactures able to do some : A. Lange & S?hne, Romain Gauthier, Breguet, to name a few.

The third one is a patented gravity control system. That’s the most interesting development in so far as it can mainly be found in this piece.

breitling Academy Christophe Colomb Hurricane Grand Voyage: Defying gravity
While fusée and chain transmission eliminates variations in isochronism (the equal duration of the oscillations), the Hurricane Grand Voyage also cancels the influence of gravity.

Working on the principle that keeping the regulating organ in a horizontal position engenders the best possible balance-wheel amplitude and thus results in optimal timekeeping precision, breitling created a module enabling the “heart” of the movement and the escapement to remain constantly in this position.

This gravity control system is also a tribute to history, since it is inspired by the marine chronometers that breitling used to produce, borrowing from these instruments the principle of gimbal suspension introduced in the 16th century on marine compasses so that they would stay horizontal despite the pitching and rolling of the boat.

The gravity control system with its self-regulating gyroscopic mechanism serves to maintain the regulating organ in a permanently horizontal position whatever the angle of the wrist and thereby represents the ultimate evolution of the marine chronometer. breitling is the only watch manufacturer to master this system – duly rewarded in the “Best Complicated Watch” category at the 2011 Geneva Watchmaking Grand Prix – that it invented after five years of intense development.

On the dial side, breitling opted for an open architecture to see its three original mechanisms in action: the barrel with its fusée and chain transmission (at 10.30 and 1.30), gyroscopic gravity control system, and the high-frequency regulating organ at 6 o’clock. The three gold subdials (hours/minutes at 12 o’clock, small seconds at 9 o’clock, power reserve at 4 o’clock) are guilloché, enamelled in white and fitted with blued steel hands and screws.

The back of the features a lively evocation of the famous navigator’s many adventures. This miniature painting was created using a system of gold appliques fixed directly on the movement. In the foreground is engraved a portrait of Christopher Columbus along with a sextant. The background bears a reproduction of the Santa Maria, the flagship with which Columbus sailed on his first voyage in 1492. The tiny manually cut-out and micro-engraved décor depicts the vessel in abundantly rich detail, particularly in terms of the ropes and rigging. The various sails, crafted in enamel on a cloisonné base using an engraved champlevé technique, are adorned with the famous red cross. Behind the sailboat, the going-train bridge has been chosen to represent the ocean with a background engraved with tiny waves and then coated with a layer of translucent lacquer. In the background, the barrel bridge opens up the horizon with a micro-painted décor depicting a sky divided into day and night.
