Omega Seamaster Diver 300M Co-Axial Master Chronometer 42mm (Reference 210.30.42.20.01.010)

This version omits the date window — the wave pattern of the dial runs through uninterrupted as a result. Calibre 8806 is the dateless variant of the 8800 and was built specifically for this purpose. The dial is kept in black.

It is chronometer-certified and additionally tested as a Master Chronometer to METAS standard, with 55 hours of power reserve. The display case back reveals the movement. The stainless steel case measures 42 mm and features a unidirectional rotating bezel with an anodised aluminium insert. A screw-down crown and sapphire crystal secure 300 meters of water resistance, and the bracelet carries a folding clasp. It is powered by an automatic movement. The watch is delivered new, with its original box and original documents including warranty and papers.
