Case and Dial Design

The watch is housed in a two-body, polished stainless steel case featuring concave lugs and a transparent back secured by eight screws, revealing the movement. A push-button is integrated into the case band at the 8 o'clock position, specifically designed to advance the second time-zone hand in one-hour increments. The watch is worn on a strap with a stainless steel double deployant clasp. The dial exhibits a complex regulator-type layout in anthracite and silver tones. Applied white gold radial Arabic numerals occupy the outer reserve. Individual subsidiary rings display the hours at 3 o'clock, a 24-hour second time-zone with day and night indication at 9 o'clock, and the seconds at 6 o'clock. An 8-day power-reserve sector is positioned at 12 o'clock. The hands are crafted from blued steel and incorporate luminous material for visibility.

Movement and Performance

Internally, the timepiece is driven by the Calibre 4RT, a rhodium-plated movement finished with fausses cotes decoration. The construction centers on twin barrels to maintain an 8-day power reserve, supported by 39 jewels. The escapement is a straight-line lever type equipped with a shock absorber and a self-compensating Breguet balance-spring. Precision is maintained through a swan-neck micrometer regulator. The monometallic balance is adjusted to perform under heat, cold, and isochronism, specifically across five positions to ensure accuracy as a chronometer.
