Description
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 coloured Roman numerals on the bezel, a silk-embossed rhodium-grey dial and a date window at the 6 o’clock position. The hands, OMEGA logo, Constellation star and facetted indexes are all blackened.
Presented on a black rubber strap, 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).
- Chronometer: Label given to a watch which has been successfully tested by an accredited and independent laboratory in order to receive a certificate compliant with the chronometer ISO 3159 standard.
- 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.
- 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).
- Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
- Transparent caseback: A transparent caseback – frequently made of sapphire – makes it possible to see the movement inside the watch.
