The Seamaster Professional Diver 300M has built a loyal fanbase since its inception in 1993. Its 21st century editions pay homage to the classic dive watch design while incorporating new materials and movements.

At 43.50mm, the black ceramic [ZrO2] case, bezel, wave-pattern dial, crown & helium escape valve deliver a distinctive, unified and sculpted aesthetic. Visibility is enhanced thru anthracite Super-LumiNova, black PVD indexes & skeleton hands with a dot at 12H, while an integrated black rubber strap & ceramic buckle complete the look. The movement can be observed through the sapphire crystal caseback window, housing OMEGA's certified Co-Axial Master Chronometer Calibre 8806.
