Design

Case and Bezel
The watch is housed in an Oyster case, which the auction description reports has undergone professional refurbishment. This maintenance process is noted to have preserved the architectural integrity of the case, specifically the thickness of the lugs and the clarity of the chamfered edges. The case shows light signs of wear, including one scratch. The watch features a bidirectional rotating bezel fitted with a bi-colored red and blue aluminum insert, often identified as the 'Pepsi' configuration. This component has also been professionally refurbished and is described as being in fantastic condition, retaining the intended color contrast for AM/PM indication.
Dial and Hands
The watch is equipped with a 'MK4' dial variant, which is stated to be in good condition. The indices are applied and contain Tritium, which has developed a significant, rich patina over time. This aging is consistent across the dial. The handset is described as matching the dial, featuring central hour, minute, and seconds hands, alongside the signature GMT fourth hand used to track a second time zone via the 24-hour scale on the bezel. The date is visible through a cyclops lens positioned at the 3 o'clock mark on the crystal.
Visible features
• Cyclops lens over the date aperture at 3 o'clock • Rotating bidirectional 24-hour bezel with red and blue insert • Luminous material on indices and hands exhibits yellowed patina • Jubilee-style metal link bracelet with integrated folding clasp
Bracelet and Clasp
The timepiece is mounted on a U.S. oval-link Jubilee bracelet, which is cited as being period-correct to the watch. The bracelet is secured with a signed blade clasp. The finish and condition of the metalwork are noted to complement the aesthetics of the case, completing the vintage presentation of the reference.
