REBORN & REIMAGINED: OUR ICONIC MARINE CHRONOMETER
Paying homage to the classic 1980s Observatory, this upgraded version follows three years of research, development, design and execution.
The chronometer features fifteen complications, including a rare flying detent tourbillon and double fusee-and-chain transmission. Extensively grained and inlaid with precious woods, the elegant case holds a distinctive dial displaying hours, minutes and seconds in separate sub-dials.
Hours. Minutes. Seconds. Time seems a straightforward concept. Yet recording the passage of time is not, as a glance at this chronometer’s 15 complications will confirm.
The chronometer’s measurement of time is achieved using a rare detent escapement, Thomas Mercer’s signature technology for almost a century. Its unparalleled accuracy and reliability is the result of very low energy consumption, low friction and lightness. To fulfill the need for worldwide accuracy, the timepiece also features a 24-world location, 24-time zone disc. At any given moment, anywhere in the world, it tells the local time.
The chronometer’s case is as refined and sophisticated as its mechanism. A stainless steel base is the foundation for a series of pillars that carry the actual mechanism. The base and columns are inlaid with Santos Rosewood and South American Ziricote, two species of rare exotic hardwoods. Above the ultra-complex movement, the dial features a pair of large, hand-made blue-steel hands and glasses made of extra-white crystal.
The case is crafted from Ziricote and Santos Rosewood and hand-polished stainless steel.
The solid brass dial has rhodium and 4N gold electroplating with gold-plated Indexes.
The Observatory Grand Complication features double gimbals, counterbalance free and double lock.
The marine chronometer’s glasses are extra-white crystal and rock crystal.
Meeting the highest standards of the horological craft, each of the 1680 brass and steel components has been meticulously manufactured, plated and bevelled. Depending on its position and function within the mechanism, each wheel, gear, lever, spring or screw has either been finished with Geneva stripes, circular graining, straight graining or polished. The mechanism is visible under any angle, without distortion.Learn More
