About This Piece

The diving watch to beat, this OMEGA Seamaster Diver 300m really is a winner. On one hand sporty, with its rubber strap and 300m water resistance, and on the other hand showing some serious style with its wave-adorned ceramic dial and monochromatic aesthetic.

Capturing the ocean spirit, the OMEGA Seamaster Diver 300m Co‑Axial Master Chronometer collection can withstand some of the harshest environments. But don’t just take our word for it.
