About the Omega 1819.51.91
The especially dramatic and enduring design concept of the OMEGA Constellation line is characterized by its famous “Griffes”, or claws, and striking dials. This model features a black dial with 30-minute and 12-hour recorders, a small seconds dial, a date window and a tachymetre scale, and is covered by a scratch-resistant sapphire crystal. The black bezel, with its Roman numerals, is mounted on a 41 mm stainless steel case, and is presented on a black rubber strap. This timepiece is powered by the Co-Axial calibre 3313.
