Omega Diver 300M Co-Axial Master Chronometer 43.5mm Watch

43.5 mm black ceramic case, self-winding movement, rubber strap

The Seamaster Professional Diver 300M became a legend upon its launch in 1993. OMEGA's 21st-century models remain true to the original dive watch's design while incorporating fascinating new materials and movements. This 43.50mm model showcases black ZrO2 ceramic. Crafted from this exceptional material, the case, bezel, wave-patterned dial, crown, and helium escape valve give the watch a sculptural look that is both uniform and distinctive. To enhance legibility without compromising the overall aesthetic, OMEGA has applied an anthracite Super-LumiNova coating to the diving scale, PVD hour markers, skeletonized hands, and 12 o'clock marker. An integrated black rubber strap with a black ceramic buckle completes this model. A case back that opens directly onto the movement provides a striking contrast. The OMEGA Co-Axial Master Chronometer calibre 8806 is also visible through the sapphire crystal case back with wavy edge.
