OMEGA Seamaster Diver 300M – A Timeless Icon, Reimagined
Since its debut in 1993, the Seamaster Professional Diver 300M has captured the hearts of watch enthusiasts worldwide. Honoring its storied oceanic heritage, the modern collection elevates the legacy with cutting-edge innovation and refined design.
This 42mm model is a stunning combination of stainless steel and 18K Sedna™ gold, showcasing a black ceramic bezel adorned with a Ceragold™ diving scale for a touch of luxury and functionality. The polished black ceramic dial features laser-engraved waves—a nod to the sea—and is completed with a date window at 6 o’clock for added practicality.
The 18K Sedna™ gold skeleton hands and raised indexes are filled with white Super-LumiNova, ensuring optimal readability in any environment. A conical helium escape valve adds to the watch’s professional diving capabilities.
Presented on a stainless steel and 18K Sedna™ gold bracelet, this timepiece is powered by the OMEGA Master Chronometer Calibre 8800, visible through the sapphire crystal on the wave-edged caseback. Certified to the highest standards of precision and performance, it embodies OMEGA’s commitment to excellence.
The Seamaster Diver 300M seamlessly combines elegance and adventure, making it the perfect companion for both ocean explorers and style aficionados.
