Omega Seamaster Diver 300M Chronograph | Titanium & 18K Gold | 2297.80

The Omega Seamaster Professional Chronograph Ref. 2297.80 is a distinctive two-tone dive chronograph from the 1990s, combining a lightweight titanium case and bracelet with 18K yellow-gold accents. The approximately 41.5mm case is paired with a blue wave-pattern dial, gold-tone hands and subdial surrounds, a gold-accented unidirectional bezel, and sapphire crystal, giving the watch a more luxurious look than the standard steel Seamaster while retaining the rugged feel of the Professional 300M line.

Powering the watch is the Omega Calibre 1164, an automatic chronograph movement based on the ETA/Valjoux 7750 architecture. It operates at 28,800 vph, offers approximately 44 hours of power reserve, and includes quick-set date, running seconds, 30-minute and 12-hour chronograph counters. The Ref. 2297.80 was designed as a serious dive chronograph with a helium escape valve and original 300-meter / 1,000-foot water-resistance rating.

Condition

Please review the photos carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, crystal wear, case wear, or other signs of use consistent with age may be present.

Please note that the clasp/buckle appears to have been slightly overpolished, and the Omega logo on the clasp is somewhat faded/softened as a result. This is being disclosed for complete transparency. Please review the close-up photographs carefully for the best representation of the clasp condition.
