Breitling own a professional team of making the brilliant movement experts in charge of developing and testing advanced technical solutions that can possibly be introduced on series-produced models. At present, there is a new high-performance movement appearing in the Superocean Heritage Chronoworks, a 100-piece limited edition interpreted in a bold all-black version.
Breitling – Superocean Heritage Chronoworks replica is made in a 46 mm matt ceramic case, equipped with water resistant to a depth of 330 feet, which displays the Chronoworks movement and its black oscillating weight through the transparent caseback. Starting from the Manufacture Calibre 01, the watch features a chronograph movement in self-winding and a column-wheel construction, a vertical coupling-clutch and an power reserve up to over 70-hour. The increase of the power reserve from 70 to 100 hours is not only practical for the owner of the watch but also show the precise time, it is necesary to wind it for four days even if not worn. In fact, the higher the power reserve, the less the force of the spring dwindles during the first 24 hours, so enhancing regularity of the movement rate.
The pointed hour-markers and the distinctive hands of the matt black dial recall the 1957 Superocean, one of the first deep-water-resistant wristwatches of the brand.The calibre has been fitted with three wheels, centre wheel, third wheel, or the fourth wheel in silicon, a material twice as light as normal and that thus makes it easier to set the movement in motion again, a phase which absorbs lot of energy.
The first optimization involved the movement chassis. These components were made from a high-tech ceramic in order to reduce friction due to the pivoting of the arbors. Thanks to an extremely low friction coefficient, the arbors can pivot directly in the baseplate and bridge holes without any wear or energy loss and also without any lubricant. As a result, it was possible to eliminate 11 out of 47 jewels. The escapement – the part of the movement where most of the energy losses take place – has been enhanced by crafting wheel and lever in silicon. This serves to reduce weight and thus inertia, as well as eliminating the need for pallet jewels. To ensure more efficient transmission of the energy from the barrel, the geometry of the two components was revisited delivering an overall 42% gain in efficiency.Another energy-loss area in a vertical coupling-clutch chronograph mechanism is the set of one arbor and two wheels measuring 2 mm in diameter responsible for connecting the base movement and the wheel bearing the sweep-seconds hand. This set displays a certain play that can lead to jerking that is generally eliminated by using a “friction spring” at the cost of a 15% energy loss. To avoid this, Breitling equipped the two wheels with elastic toothing molding the shape of the opposite teeth, by means of a nickel-phosphorous structure.
The variable-inertia balance, adjustable via four tiny gold weights situated around the rim, is insensitive to temperature variations hence maintaining the same rating precision in every circumstances. Equipped with a woven rubber strap inspired by the original woven steel bracelet, the Breitling Superocean Heritage Chronoworks replica is almost identical to the genuine piece, you would like.
