OMEGA® Speedmaster Moonwatch Professional 42 mm, steel on steel

In line with the brand’s deep connection to the sea, OMEGA is a proud partner to Nekton, a not-for-profit research foundation committed to the protection and management of the world’s oceans.

This 42 mm Seamaster Diver 300M, released in support of Nekton, has a polished-brushed stainless steel case and laser ablated black ceramic [ZrO2] dial, matt finished with polished waves in positive relief. The uni-directional rotating bezel is in grade 5 titanium and features a laser ablated diving scale.

The caseback, embossed with the Nekton submarine medallion, is oriented with OMEGA’s innovative NAIAD LOCK. An integrated black rubber strap with polished-brushed buckle beautifully complements the black ceramic dial.

Powering OMEGA’s tribute to Nekton is the exceptional Master Chronometer Calibre 8806. Tested and approved at the industry’s highest level.

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 42 mm model is crafted from stainless steel and 18K yellow gold, and includes a black ceramic bezel with a Ceragold™ diving scale. The dial is also polished black ceramic and features laser-engraved waves and a date window at 6 o’clock.

The skeleton hands and raised indexes are 18K yellow gold and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.

The watch is presented on a black rubber strap and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
