Omega Seamaster Diver 300M Ref.


Pre-Owned Omega 42mm Seamaster Diver 300M, Blue Dial, Stainless Steel Bracelet, Ref.

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.

This 42mm model is crafted from stainless steel and includes a blue ceramic bezel with a white enamel diving scale. The dial is also polished blue ceramic and features laser-engraved waves and a date window at 6 o’clock.

The skeleton hands and raised indexes are rhodium-plated and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.

The watch is presented on a stainless steel bracelet and is driven by the Omega Master Chronometer Caliber 8800, which can be seen through the sapphire-crystal on the wave-edged caseback. Omega’s Master Chronometer caliber 8800 is packed with all the innovations that Omega introduced since the 1999’s co-axial escapement: Si14 silicon balance spring, anti-magnetic up to 15,000 gauss and a power reserve of 55 hours. The finish on this movement is beautiful, with the Geneva waves in Arabesque and blackened screws, barrel and balance wheel. This excellent watch from circa 2021 includes its original box and papers.

Omega is one of the world’s most recognizable luxury watch brands.  Although founded in 1848, the company did not become known as Omega until 1894, when the company took the name of its highly successful new watch movement.  The revolutionary movement used a single crown for both winding and time setting.  Success followed success when in 1905, due to its commitment to accuracy, Omega became the official timekeeper for Swiss sporting events.  Later in 1932, Omega became the official timekeeper of the Olympic Games.  To mark Omega’s 100th year anniversary, Omega introduced the watch that would become one of the world’s most popular watches, the Seamaster.  While these are remarkable achievements, the watch that made Omega a legend among watchmakers was the Speedmaster, the only watch to survive the brutal NASA testing requirements and the only watch certified by NASA for use in Space.  It is no surprise that Omega watches are recognized today as spectacularly rugged tool watches hiding in a luxury watch.
