Brushed 18K white gold dial plate, at 3 "guilloché" matte silver ring dial with painted Arabic numerals for the hours and minutes, apertures at 6 for the constant force remontoir and at 9 for the tourbillon regulator under a polished steel bridge, up-and-down indication at 11. Blued steel "Journe"-style hands. M. Cal. 1498, rhodium-plated, "fausses côtes" decoration, 25 jewels, lateral lever escapement with one-minute tourbillon regulator with "A"-shaped tourbillon frame and polished steel bridge, "Gyromax"-type balance with 4 timing weights, self-compensating free-sprung Breguet balance-spring with Phillips terminal curve. The constant-force remontoir with an 18K gold wheel seeks extreme precision by equalizing the mainspring's varying power supply. A blade spring, controlled by a spinning vane, is armed once a second by the force of the mainspring, feeding a steady flow of power to the balance for a more constant rate. Dial, case and movement signed. Diam. 38 mm. Thickness: 10 mm.
