Omega Speedmaster Moonphase 304.30.44.52.01.001 44.25 mm Steel Black Dial Watch for Men

At 6 o'clock on this Speedmaster Moonphase, a microstructured metallic crystal disc renders the moon in high resolution, one of two photo-realistic moons on the watch. Rhodium-plated hands and indexes stand on a sun-brushed black dial, set in a 44.25 mm stainless steel case beneath a black ceramic bezel ring with a Liquidmetal™ tachymeter.

The self-winding Calibre 9904 is a column-wheel chronograph with Co-Axial escapement and METAS Master Chronometer certification, resistant to 15,000 gauss. Alongside the moonphase it shows the date by hand, small seconds, and 12-hour and 60-minute recorders, with a 60-hour power reserve. The steel bracelet has a polished-brushed foldover clasp with comfort setting; water resistance is 100 metres.
