The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, as well as the “claws” on the side of the case.
This 41 mm stainless steel model features a polished blue ceramic bezel with Roman numerals in Liquidmetal™, a sun-brushed blue dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and facetted indexes are all rhodium-plated.Presented on a blue leather strap with rubber lining, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8900, visible through the domed scratch-resistant sapphire crystal.\

FEATURES
Anti-magnetic
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronograph
The chronograph function is a mechanism for measuring time intervals. A chronograph watch can therefore be used to time events while displaying the time like any traditional watch.
Chronometer
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Date
The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
Helium escape valve
Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Regatta timing
A watch function which allows the easy reading of the critical regatta time intervals at glance.
Screw-in crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Small seconds
A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.
Transparent caseback
A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel
A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
