Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design.

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).
