Thomas Mercer Crystal Chronometer

Thomas Mercer presents the Crystal, a brand new marine chronometer paying tribute to the 1980’s eponymous model.

Its distinctive case features a rhomboidal-shaped mechanism floating inside a glass tube.

The original timepiece stood for its ground-breaking, horizontally laid out, eight-day movement mounted within a cylindrical glass revolving case on a rectangular plinth. The dial was partially skeletonised, boasting a silvered Roman chapter ring and eccentric subsidiary dials for seconds and power reserve indicator.

Faithful to its motto “Respecting the past, reinventing the future”, Thomas Mercer now evolves the Crystal by introducing a set of innovative features.

The gold-plated brass frame gives way to elegant stone elements made of orange onyx. This rare variety hails from Mexico and stands for a low level of inclusions, making it almost pure and organic to the sight.

The choice of onyx is also extended to the dial, conferring a refined look whilst maintaining its original sheerness. Such exclusive touch is enriched with elegant applique numbers and counters.

In the ever-present blend of tradition and innovation, the mechanism adds annual calendar and sky chart to the original indications of power reserve and offset seconds.

In perpetuating the brand’s maritime heritage, the sky chart is a homage to antique navigators who, in the olden days, charted their plot course using the stars in combination with a marine chronometer.

The star map shows – in real-time – the constellations over the skies of the Greenwich Observatory or, at request, over a location of the Client’s choice.

Further to the new complications, the movement flaunts an innovative winding and adjusting system. The provisions for winding and setting the hands through the rear of its cylindrical glass are now replaced by two cutting-edge, wristwatch-inspired crowns. These crowns can be pulled in-out and rotated to respectively wind the mechanism and regulate the indications of hour, minute, annual calendar and sky chart.

As per the brand’s sign of distinction, the mechanism offers an all-round view and features Thomas Mercer’s sine-qua-non chain-fusee drive and spring detent escapement.

The Thomas Mercer Crystal Chronometer measures 295 x 130 x 150 (h) mm to 400 x 260 x 260(h) mm.
