The Marine Tourbillon Chronograph is back in the news with new specifications incorporating the latest advanced horological technology so as to raise its performances beyond compare and turn this striking design into a epitome of creative verve, innovation and refinement.
Fitted in a pink gold case, handwound Breguet calibre 554.3 has had its frequency upped to 3 Hertz. It drives a spectacular tourbillon regulator at 12 o’clock on the dial whose totally original carriage boasts an upper bridge and pillars made of titanium. The movement also incorporates the latest in isochronous refinement, not least a balance spring, an escape wheel and a lever made from silicon, a magnetically inert material.
Silicon greatly reduces the inertia of the lever and escape wheel and does away with the need for lubrication. The balance spring features a centre coil, variable pitches and sections and an integrated collet. The greatest challenge in the production of silicon balance springs is the determination of its temperature coefficient, i.e. keeping the watch’s rate steady whatever the temperature. These components, for which patent applications are outstanding , markedly improve the movement’s isochronism and produce results normally achieved only with a BREGUET overcoil spring.
So sophisticated a mechanical masterpiece called for exceptional design and finish in the best Breguet tradition. The shaped pushpieces and black rhodium plated dial featuring a delicately engine-turned wave pattern allude discreetly to the origins of the collection. Opentipped Breguet hands coated with a luminescent compound sweep over a chapter ring with applied numerals and luminescent dots. The chronograph totalizers are positioned at 3 and at 6 o’clock on the dial while the running seconds are read off the tourbillon carriage at 12 o’clock. A pink gold bracelet or black rubber strap with gold clasp completes this study in refinement combining multiple cultural references and a dash of contemporary spirit.
