Seiko Think The Earth WN-1 Quartz Wristwatch & Box

A vintage Seiko Think The Earth WN-1 quartz wristwatch, designed to function as both a wristwatch and a desk clock. This unique timepiece features a 45mm titanium case with a removable 24-hour bezel, domed Hardlex crystal, and an inner rotating globe. Powered by a high-precision quartz movement, the watch uses three reducing gears in the drive train, enabling the rotation of the globe. The hook time zone hand and orange ping-pong ball minute hand are located on the dial's periphery, while the hour indicator rotates counterclockwise in sync with the 3D Earth model, which completes one full rotation per day. The watch includes a black fabric strap with a titanium pin buckle and comes in its original fitted box.
