A cornerstone of Omega’s 2018 introductions, the Seamaster Diver 300M line—introduced in 1993 and completely overhauled this year—now features a larger 42 mm case and a slew of aesthetic and technical updates, including a ceramic diving bezel, polished ceramic dial, and newly patented conical helium escape valve. The timepiece also has a hidden perk: its Master Chronometer Calibre 8800, known for its superior precision and magnetic resistance.

Introduced on the eve of World Oceans Day, the Bremont Waterman is a limited-edition dive watch from the U.K.-based brand and its ambassador, Mark Healey, a big-wave surfer, freediver and ocean environmentalist who helped test the timepiece while riding some of the world’s biggest waves. Equipped with a unidirectional rotating bezel with Super-LumiNova, an automatic helium escape valve and crown protector, and water resistance to 500 meters, the 43 mm stainless steel watch also boasts GMT functionality.
