Omega Seamaster Diver 300M Co-Axial Master Chronometer 42mm (Reference 210.30.42.20.10.001)

Green arrived late in the Seamaster line and has since become one of the most sought-after colors. The laser-etched wave pattern sits within the surface and changes its depth with the incidence of light.

Calibre 8800 is Chronometer-certified and additionally tested as a Master Chronometer to the METAS standard. It offers 55 hours of power reserve and displays the date alongside the time. The stainless steel case measures 42 mm and features a unidirectional rotating ceramic bezel as well as a display case back. A screw-down crown and sapphire crystal ensure 300 meters of water resistance, and the bracelet carries a folding clasp. The watch is driven by an automatic movement. The watch is delivered new, with its original box and original documents including warranty and papers.
