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.

The pushers are also polished black ceramic, as well as the dial which features laser-engraved waves and a date window at 6 o’clock. The subdial hands are rhodium-plated, along with all other hands and indexes which are filled with white Super-LumiNova. The watch is presented on a stainless steel bracelet and is driven by the OMEGA Master Chronometer Calibre 9900, which can be seen through the sapphire-crystal on the wave-edged caseback.

Master Chronometer

Bringing together luxurious design and ground-breaking functionality, OMEGA have earned a reputation for producing world class timepieces that never fail to make a lasting impression.

In 1848, when Louis Brandt sat down to create the company’s very first watches, his ambition was to produce the most accurate movements possible. For OMEGA, precision is still the truest mark of mechanical watchmaking quality.

Since 2015, OMEGA’s Master Chronometer testing for each individual timepiece has provided customers with total transparency and a proven precision and performance they can trust.
