Omega Tourbillon Co-Axial Chronometer Numbered Edition 44 mm Blue Dial (528.53.44.21.03.001)

Description

An extraordinary expression of the art and craft of watchmaking, this incredible timepiece combines classic tourbillon technology with expressive contemporary design.

The newly-designed 44mm tourbillon case is crafted from 18K Sedna™ gold, as are the “flying hands”, which are applied to a sapphire crystal, and the brushed seconds hand that is set within the tourbillon titanium bridge.

The dial and the inner ring are sun-brushed 18K Sedna™ gold treated with blue PVD, while the elegant 18K Sedna™ gold second markers form a ring in a railroad design obtained by laser ablation. The words “Co-Axial Chronometer” and the OMEGAsymbol in 18K Sedna™ gold were revealed when the PVD treatment was removed.

Presented on blue leather strap with an 18K Sedna™ gold clasp, the outstanding chronometric performance is achieved through OMEGA’s exclusive calibre 2638.

Finally, the caseback is embossed with a medallion featuring Chronos, the God of time, and with the tourbillon’s own serial number.

Features

• Chronometer

  Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

• Numbered edition

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

• 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.
