Omega Seamaster Professional 300m Chronograph Model 25998000 Appraisal

Omega Seamaster Professional 300m Chronograph (Model 2599.80.00)

This is a high-grade Omega Seamaster Professional Chronometer 'James Bond' style dive watch, likely dating from the late 1990s to early 2000s. The timepiece is constructed with a robust stainless steel case measuring approximately 41.5mm, featuring a unidirectional blue rotating bezel with an elapsed time scale. The dial is the iconic deep blue with a 'wave' pattern texture, adorned with luminous round hour markers and skeletonized hands. Chronograph functionality is presented through three sub-dials at the 6, 9, and 12 o'clock positions, with a date window located at 3 o'clock. The watch features a helium escape valve at 10 o'clock and screw-down pushers for water resistance up to 300 meters. The bracelet is a five-link 'Bond' style brushed and polished stainless steel with a fold-over clasp. Condition-wise, the watch shows signs of regular wear, including superficial scratches (scuffs) on the lugs, bezel surface, and pushers. The sapphire crystal appears intact, and the lume on the markers shows a slight creamy patina consistent with age. Notable markings include the Omega logo, 'Seamaster Professional Chronometer', and '300m/1000ft' on the dial, and 'Swiss Made' at the bottom. This model is powered by the Omega Calibre 1164 automatic movement.
