Tourbillon Co-Axial Master Chronometer 43 mm Black Dial Numbered Edition

Description

Handcrafted by a select group of horologists at OMEGA’s Atelier Tourbillon in Switzerland, this extraordinary timepiece is OMEGA’s first-ever manual winding central tourbillon to be Master Chronometer certified.

Cased in a blend of 18K Sedna™ gold and 18K Canopus Gold™, it features an 18K Sedna™ gold bezel and a sun-brushed dial in the same lustrous material treated with black PVD.

Its indexes, polished minute and hour hands are in applied 18K Sedna™ gold. An 18K Sedna™ gold polished seconds hand is set in the tourbillon titanium bridge. The crown, also in polished 18K Sedna™ gold, features a Ω set in 18K Canopus Gold™.

Presented on a black leather strap with polished 18K Sedna™ gold buckle, this exceptional example of the watchmaker's art looks sensational from all angles, as the sapphire crystal caseback allows a view of the 18K Sedna™ gold movement: OMEGA’s Master Co-Axial Chronometer Calibre 2640.

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 undergone precision tests and received a certificate from an official body (COSC).

• 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).

• Numbered edition

  A watch series each of whose pieces is numbered sequentially in the order it is produced.

• Power reserve indicator

  A dial or gauge on the watch which indicates how much time remains before the mainspring must be wound or the battery changed.

• Tourbillon

  An ingenious principle which solves the tricky problem of adjusting mechanical watches. All the components of the escapement (escape wheel, pallets wheel, pallets fork and balance spring) are grouped together in a small mobile cage which makes one rotation per minute. This eradicates any differences in rate due to different positions of the watch and thus guarantees optimal precision for a mechanical watch.

• Transparent case back

  A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
