Description
The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and “claws” on the case.
Standout features on this 29 mm model are the dial made from natural blue Aventurine stone and the shimmering leather strap in matching colour.
Crafted in stainless steel and 18K Sedna™ gold, it has a diamond-paved bezel and a date window at 6 o’clock. The hands, hour markers, OMEGA logo and Constellation star are in 18K Sedna™ gold.
At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8700, 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.
- Diamonds: The hardest, most luminous precious stone whose value is calculated according to the 4C criteria: Cut – Carat – Clarity – Color.
- 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).
- Transparent caseback: A transparent caseback – frequently made of sapphire – makes it possible to see the movement inside the watch.
