Description
The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, “claws” on the case and mono-rang bracelet.
This 29 mm 18K Sedna™ gold and stainless steel model features a bezel engraved with Roman numerals, crystal white silvery dial with diamond hour markers and a date window at the 6 o’clock position. The hands, OMEGA logo, Constellation star and diamond holders are also 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.
