Omega Seamaster Diver 300M Chronograph | 41.5mm Blue Wave Dial | Ref. 2225.80 |

The Omega Seamaster Diver 300M Chronograph Ref. 2225.80 combines the classic neo-vintage Seamaster aesthetic with full chronograph functionality. It features a 41.5mm stainless-steel case, blue wave-pattern dial, matching blue unidirectional dive bezel, sapphire crystal, and stainless-steel bracelet. The dial includes luminous hands and markers, a date window at 3 o’clock, and three chronograph registers for running seconds, 30-minute timing, and 12-hour timing.

Powering the watch is the Omega Calibre 1164, a self-winding chronograph and certified chronometer with approximately 44 hours of power reserve. The watch also includes a screw-down crown, helium escape valve, and an original 300-meter / 1,000-foot water-resistance rating, giving it the robust dive-watch capability expected from the Seamaster Professional line. This example is accompanied by its Omega card.
