Omega Seamaster Diver 300m Co-Axial Master Chronometer Watch
This 42mm diver features a green ceramic dial with laser-engraved wave pattern and applied rhodium-plated indexes filled with white Super-Lumi Nova. The matching green ceramic unidirectional bezel houses white enamel diving markings, whilst the domed sapphire crystal incorporates anti-reflective coating on both sides. Water resistance reaches 300 metres, supported by a helium escape valve with conical design. The watch sits on a green rubber strap and includes a date window at 6 o'clock.
Movement and construction centre on the OMEGA Master Chronometer Calibre 8800, visible through the exhibition caseback with wave-textured edge. This Co-Axial certified movement meets chronometer standards for precision, rate accuracy and magnetic resistance. The polished case back and skeleton hands complete the specification, echoing Omega's diving watch lineage whilst incorporating contemporary materials and finishing techniques.
