Driven by its passion for the deep sea, OMEGA is proud to collaborate with Nekton, a non-profit research foundation committed to the protection and management of the oceans. As a token of OMEGA's support for the Nekton foundation, this Seamaster Diver 300M 42mm features a polished and satin-finished stainless steel case as well as a laser-engraved black ZrO2 ceramic dial with a matte finish, decorated with its iconic polished waves in relief. Made from grade 5 titanium, the unidirectional rotating bezel features a laser-engraved diving scale. The caseback stamped with the medallion representing the Nekton submarine is oriented using OMEGA's innovative NAIAD LOCK system. The integrated black rubber strap closed with a polished and satin-finished buckle matches perfectly with the black ceramic dial. This OMEGA model designed as a tribute to the Nekton foundation is powered by an exceptional movement that has passed the most demanding tests in the entire watchmaking industry: the Master Chronometer8806 caliber.
