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.
