The Omega Seamaster Diver 300M Co-Axial GMT Chronograph reference 212.30.44.52.01.001 is a highly technical certified pre-owned luxury watch that combines professional dive performance with advanced chronograph and GMT functionality. Designed for travellers and watch enthusiasts who appreciate both precision and versatility, this model is one of the most sophisticated interpretations of the Seamaster Diver 300M collection.

This timepiece is housed in a solid 44 mm stainless steel case, paired with a unidirectional ceramic bezel featuring a laser-engraved diving scale.

True to its professional diving roots, the watch is water-resistant up to 300 metres (1,000 feet) and equipped with a helium escape valve.

This pre-owned luxury watch is presented in very good condition and comes as a full set, including the original Omega box and papers. The stainless steel bracelet remains in excellent overall condition, reflecting careful wear.

This Omega Seamaster Diver 300M GMT Chronograph is making it a compelling opportunity for collectors seeking a versatile, high-performance Seamaster.
