This relatively obscure Seamaster reference captures the best of Omega's early-1970s sports-watch design. Its exceptionally preserved blue acrylic bezel, deep midnight-blue-to-black dial, creamy tritium patina, oversized screw-down crown, and rare original bracelet give it tremendous character. It is a striking vintage diver unlike anything in Omega's current catalog.
Restoration Notes
The Cal. 1002 automatic movement received a complete service in October 2025 using industry-standard methods, Moebius lubricants, and proper watchmaking tools. It was fully disassembled, cleaned, inspected, lubricated, reassembled, regulated, and functionally tested. The original tritium in the hands was stabilized from behind with lume binder, new gaskets were installed, and the watch passed a 6 ATM pressure test following service.

Condition Notes
Case
Very good vintage condition with the original sunburst finishing still visible, accompanied by minor scuffs and surface scratches throughout. The original caseback retains its Omega Seahorse medallion and has no personal engraving. The original oversized screw-down crown is in beautiful condition and has been fitted with a new gasket. The bidirectional 60-click blue acrylic bezel is exceptionally well preserved, with no cracks and only a few minor flea bites.
Crystal
Mineral crystal is in excellent condition, with no notable scratches, chips, or scuffs.
Dial and Hands
Original dial has an exceptionally deep gloss-black to midnight-blue appearance, with even creamy patina across the original tritium lume. Only a few very minor and stable spider-web fractures are visible under close inspection. The original hands show matching tritium patina; their lume was stabilized from behind with binder to prevent further degradation.
Movement
Omega Cal. 1002 high-beat automatic movement with quick-set date and hacking seconds. Fully serviced in October 2025 and running well since service.
Band / Strap
Original and uncommon signed Omega bracelet, believed to have been produced by JB Champion for the United States market. It appears to retain all links and should accommodate wrists up to approximately eight inches.
Gaskets / Seals
New gaskets were installed, and the watch subsequently passed a pressure test to 6 ATM. This records its performance at the time of testing but does not guarantee continued water resistance.
