Seamaster Master Chronometer 45.5mm O-MEGASTEEL Watch

This 45. 5 mm model in robust O-MEGASTEEL features a polished black ceramic bezel with its diving scale in Liquidmetal™. Through the protuberant and domed sapphire crystal, the lacquered gradient dial transitions from blue to black, and has been given 18K white gold hands and hour markers, which are all coated with white Super-LumiNova. The watch is set on an O-MEGASTEEL bracelet with OMEGA's patented extendable foldover rack-and-pusher with complementary length adjustment and an extra diver extension, while on the caseback's Grade 5 titanium medallion, there is a laser-engraved Sonar emblem with the iconic OMEGA Seahorse at its centre. Inside, the watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8912.
