Omega Constellation 131.30.41.21.01.001 41 mm Steel Black Dial Watch for Men

The all-steel Constellation 131.30.41.21.01.001 takes a monochrome approach: a polished black ceramic bezel, its Roman numerals rendered in Liquidmetal™, surrounds a sun-brushed black dial. Hands, facetted indexes, OMEGA logo and Constellation star are in 18K white gold, the date appears at 6 o'clock, and the 41 mm case carries the familiar claws and half-moons.

A stainless steel bracelet with foldover butterfly clasp and comfort setting completes the design. The self-winding calibre 8900 inside is a Co-Axial Master Chronometer certified by METAS, resistant to magnetic fields of 15,000 gauss, with two barrels in series delivering 60 hours, a time-zone function, and a rhodium-plated rotor and bridges decorated with Geneva waves in arabesque. Water resistance is 50 metres.
