The 33,8 mm 14-karat yellow gold case shows only minimal wear, The screw-down caseback, marked with Time Zone B, Hamilton Watch Co., Lancaster PA., displays the correct serial numbers and manufacturer markings. The plexiglass is in perfect condition. The silvered dial has Hamilton’s innovative US time-zone configuration.

This mechanism, attached to the hour wheel, rotates with the hour hand, enabling simultaneous time reading across zones without manual adjustment. The dial demonstrates minimal aging with only a very light and uniform patina. The Swiss-made Hamilton caliber 661 automatic movement powers this timepiece.
