Omega Seamaster 300M Co-Axial Master Chronometer 210.30.42.20.01.010 (Milanese, 42mm)
The Seamaster 300M reference 210.30.42.20.01.010 pairs Omega's iconic dive-watch silhouette with a polished Milanese mesh bracelet — a configuration that softens the tool-watch profile without compromising the 300 m dive rating, helium escape valve, or Master Chronometer certification that define the modern Seamaster line. The Milanese-bracelet execution combines the lacquered black wave-pattern dial with brushed-and-polished mesh for a finish that reads equally well in dive kit or under a cuff.
- Reference: 210.30.42.20.01.010
- Case: 42 mm stainless steel
- Bezel: Black ceramic with white enamel diving scale, unidirectional rotating
- Dial: Black ceramic with laser-engraved wave pattern, applied indexes, and luminous baton hands
- Crystal: Domed sapphire with anti-reflective treatment
- Movement: Omega Co-Axial Master Chronometer Calibre 8800, self-winding mechanical with Co-Axial escapement
- Power reserve: Approximately 55 hours
- Antimagnetism: Resistant to magnetic fields up to 15,000 gauss (METAS certified)
- Functions: Hours, minutes, seconds, date
- Bracelet: Stainless steel Milanese mesh with polished and brushed finishing
- Clasp: Omega adjustable folding clasp
- Helium escape valve: 10 o'clock position
- Water resistance: 300 m
- Year manufactured: 2024
- Country of origin: Switzerland
The Milanese configuration is the most distinctive of the modern 300M Co-Axial Master Chronometer family, offering a finish rarely seen on contemporary dive watches and a fluid drape that contrasts the architectural ceramic bezel and wave-engraved dial. This example is presented as a full set — original Omega presentation box and papers — in excellent pre-owned condition with minimal signs of wear on the case and bracelet.
