Omega Seamaster Diver 300M Chronograph 210.30.44.51.03.001 44 mm Steel Blue Dial Watch for Men

In blue, the 44 mm Diver 300M chronograph reference 210.30.44.51.03.001 uses polished blue ceramic for the bezel, the pushers and the dial. The bezel's diving scale is white enamel, and the dial combines laser-engraved waves with a date aperture at 6 o'clock and rhodium-plated hands and indexes filled with white Super-LumiNova.

The steel bracelet closes with a foldover clasp, comfort setting and diver extension. Calibre 9900 inside pairs a column wheel with a Co-Axial escapement and is certified as a Master Chronometer by METAS, resistant to 15,000 gauss; two barrels in series give 60 hours of power reserve. It shows small seconds and 12-hour and 60-minute recorders, adds a time-zone function and is water resistant to 300 metres.
