Design
- Case and Dial
- The timepiece is housed in an 18K pink gold, two-body case that is polished and features straight lugs. The back is a snap-on type. An inclined bezel is fixed to the case, displaying painted Arabic numerals and triangular indexes, which are utilized for the 12-hour time reading. The dial is a two-tone design containing applied gold dart indexes and an internal 24-hour track. A central revolving disc features the names of 24 international cities in blue, with a specific red mark positioned between Auckland and Midway to indicate the date line. The hands are fashioned from blued steel and are luminous.

- Movement and Function
- The watch is powered by the Caliber 28.5 N 21 T, a copper-colored, self-winding movement featuring 17 jewels. It is equipped with a straight-line lever escapement, a monometallic balance, a shock-absorber, and a self-compensating Breguet balance-spring. Winding is facilitated by a bumper rotor mechanism. Operational mechanics involve the hour hand performing one full rotation every 12 hours, allowing the user to read the time against the bezel graduations. Simultaneously, the inner disc, which displays the names of 24 cities, completes one rotation every 24 hours to track local times.
