Constellation Co‑Axial Chronometer 27 mm

With a name inspired by the stars, the Constellation has been a symbol of luxury since 1952. For this collection, OMEGA has looked to both the sky above and the ocean below, to create a beautiful collection of timepieces with Tahiti mother-of-pearl dials.

Along with its alluring colour, the dial of this 27mm model also features 11 diamond indexes. There is also the very unique placement of a date window at 6 o'clock.

The case and bracelet are made from stainless steel, which includes the iconic "claws" of the Constellation set on a diamond paved bezel.

The timepiece is driven by the OMEGA Co-Axial Calibre 8520 which can be seen through a stunning sapphire crystal caseback.
