HURRICANE GRAND VOYAGE

CHARTING A COURSE TOWARDS THE EXCEPTIONAL
The counterweight of the gravity control system is adorned with a micro-painted depiction of the Southern hemisphere.
TECHNICAL SOPHISTICATION REIGNS SUPREME ON THE FRONT
Engraving is followed by the delicate art of applying the lacquer.
THE BACK IS AN OPEN TRAVEL INVITATION
The manually micro-engraved décor portrays the vessel in an amazing wealth of details.
In the foreground, the finely engraved portrait of Christopher Columbus.
The various sails, crafted in enamel on a cloisonné base using an engraved champlevé technique, are adorned with the famous red cross.
THE QUEST FOR PRECISION AT THE VERY HEART OF THE MOVEMENT
The majority of 16th, 17th and 18th century pocket watches were equipped with a fusée, but today very few watch manufacturers are capable of transposing and fitting this mechanism within the confines of a wristwatch. With the Academy Christophe Colomb Hurricane Grand Voyage, stemming from two full years of development, Zenith has now entered this highly exclusive club.
Transmission between the barrel and fusée is handled by an 18 cm-long chain comprising 585 parts. This highly complex construction features alternating double and intermediate links. Once assembled, it is capable of withstanding a traction force of more than 3 kilos.
Throughout the power reserve, the mainspring transmits its energy to the fusée via a chain that wraps itself around the barrel. By adjusting the variations in tension, the fusée regulates the force that is passed on to the going train – and thence to the silicon escape-wheel fitted inside the gyroscopic carriage. While it takes more than 50 hours (the power-reserve duration) for the chain to wrap itself around the barrel, winding via the stem provides a fascinating sight. These few seconds enable the fusée and the barrel to turn in opposite directions so that the chain wraps itself back around the fusée.
The shape of the fusée was dictated by the optimal force that the Zenith master-watchmakers wished to give the barrel. Its grooved conical contours as well as its dimensions are the result of lengthy and particularly complex complications performed for each of the seven construction stages. This fusée could doubtless never have been created without the full integration of all professions (notably including movement prototype making) cultivated in the Manufacture Zenith, nor without the use of sophisticated equipment. Such is indeed one of the core strengths of an integrated Manufacture.
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, Zenith devised and patented a revolutionary module enabling the “heart” of the movement and the escapement to remain constantly in this position.
An avant-garde system brilliantly illustrating the creative daring of the Manufacture, the gravity control system is also a tribute to history, since it is inspired by the marine chronometers that Zenith used to produce, borrowing from these legendary 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. The brand with the guiding star 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.
A STYLISH PRESENTATION BOX
A magnificent ocean voyage and a splendid voyage to the heart of the infinitely small: with this limited edition combining fine watchmaking and artistic crafts, Zenith is setting out to conquer fascinating new horizons, inspired as ever by a blend of daring, authenticity and pleasure.
