OMEGA Seamaster Diver 300M | 42mm Stainless Steel | Ref. 210.30.42.20.04.001

The OMEGA Seamaster Diver 300M Ref. 210.30.42.20.04.001 is one of the most recognizable modern dive watches in OMEGA’s collection, combining professional diving capability with contemporary luxury and Master Chronometer precision. First introduced as part of the updated Seamaster Diver 300M line, this model features the highly sought-after white ceramic dial paired with a contrasting black ceramic dive bezel, creating a striking monochromatic design that has become a favorite among collectors and enthusiasts.

Crafted from stainless steel, the 42mm case showcases OMEGA’s signature blend of brushed and polished surfaces for a refined yet rugged appearance. The unidirectional rotating bezel is fitted with a polished black ceramic insert featuring a white enamel diving scale for exceptional durability and legibility. A screw-down crown and helium escape valve reinforce the watch’s professional diving credentials while maintaining the iconic Seamaster silhouette.

The beautifully executed white ceramic dial features OMEGA’s laser-engraved wave pattern, a hallmark of the modern Diver 300M collection. Black skeletonized hands filled with Super-LumiNova, luminous applied indexes, and a discreet date window at 6 o’clock provide outstanding readability in all lighting conditions while preserving the balanced symmetry of the dial.

Powering the watch is the OMEGA Co-Axial Master Chronometer Calibre 8800, an in-house automatic movement certified by METAS to the industry’s highest standards. Featuring the revolutionary Co-Axial escapement, silicon balance spring, and resistance to magnetic fields up to 15,000 gauss, the movement delivers exceptional precision, reliability, and long-term performance. A sapphire exhibition caseback reveals the beautifully decorated movement with Geneva waves in arabesque.

Completing the watch is OMEGA’s stainless steel bracelet with alternating brushed and polished finishes, secured by a butterfly folding clasp for exceptional comfort and a seamless fit on the wrist.

Offered as a Full Set, this example includes the original OMEGA inner and outer boxes, warranty cards, pictogram cards, instruction manuals, and accessories, making it an outstanding opportunity for collectors and enthusiasts seeking one of the most versatile modern luxury dive watches available.
