Omega | Seamaster Diver 300M Chronograph Titanium 18kt Gold | Ref. 22978000 (2297.80.00) – Full Set – Service 2026

Omega Seamaster Diver 300M Chronograph Titanium 18 kt. Gold Concept & History The Reference 2297.80.00 represents a significant era in professional dive watches. In the early 1990s, the manufacture revolutionized the segment by combining advanced alloys with mechanical complexity. The concept aimed for extremely durable instruments. This specific model, delivered around 1993, combines functional diving architecture with an exclusive bicolor appearance and marks a turning point in the construction of professional instruments for maritime use. Caliber & Technology At the heart of the architecture, the automatic works Omega Caliber 1164, which has been refined through extensive modifications based on a proven structure. 44 hours power reserve and COSC certification, the movement delivers an exact chronometer performance. Its technical integrity is evident in a stable amplitude and robust, water-operable chronograph pushers. A documented service from 2023 attests to the excellent condition and absolute reliability of this mechanical construction. Case & Material The 41.5 mm brushed metal housing consists of Titanium Grade 2, supplemented by massive accents from 18 kt yellow gold. This fusion reduces its own weight while maximizing corrosion resistance. A key design feature is the manually operated helium exhaust valve, paired with a pressure resistance of 30 ATM (300 Meters). The scratch-resistant sapphire crystal, the solid screwed case back, and the non-slip rotating bezel underscore the uncompromisingly functional character of this dive watch. Aesthetics & Readability The blue dial with its characteristic wave pattern creates a strong contrast with the set totalizers. Skeletonized hands and applied luminous indices guarantee uncompromising legibility, while the recessed rehaut adds optical depth to the watch face. The link bracelet made of Titanium and 18 kt yellow gold completes the design and secures the watch to the wrist with a folding clasp featuring an integrated diver's extension. The visual presence reflects pure exclusivity. All photos show exactly the item we offer - no stock images! This item is taxed in accordance with § 25 A UStG - VAT cannot be shown.
