The 39.5mm diameter solid three-body case, winglet-style strap lugs, and flat angled bezel are polished. The center of the dial is navy blue lacquered with concentric hand-guilloche historical basket-weave texture, white gold applied baton hour markers, and white gold luminous dauphine hands with lapped flanks. It has an outer night/day 24-hour GMT ring with a gold crescent moon at the 24-hour position and a yellow gold sun emblem at the 12, and a red indicator dot for the 24 different time zones/cities on a blue outermost reserve. There is also a central chronograph hand with an instantaneous 30-minute counter located at 6 o’clock. There is a rectangular push button at 10 o’clock for the updated modern city/time zone ring, a two-position pull out winding crown, and an exhibition sapphire display beveled case back. Because the chronograph hand is powered via a vertical clutch, it can also be used as a permanently running seconds hand without risking undue wear and without affecting the rate, accuracy, and power reserve of the watch. It has a minimum power reserve of 48-hours, and it’s water resistant to 30 meters/100 feet. The 12mm thick case, dial, and movement are all signed.
