Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. This 44 mm chronograph is a Numbered Edition model and is built from grade 2 titanium, 18K Sedna? gold and tantalum, which can be found on the base of the bezel and the middle links of the bracelet.
The 18K Sedna? gold bezel ring features a laser-ablated diving scale, while the polished blue ceramic [ZrO2] dial is distinguished by laser-ablated waves, a date window at 6 o??clock, and subdial rings with touches of 18K Sedna? gold.
The side of each case includes an 18K Sedna? gold plate engraved with each unique Numbered Edition number. Turning the watch over reveals an OMEGA Seahorse, which has been laser-engraved and lacquered white on the sapphire crystal. Through the glass, you can see the OMEGA Co-Axial Master Chronometer Calibre 9900, certified by the Swiss Federal Institute of Metrology (METAS).
