OMEGA Speedmaster Co-Axial Chronograph Orange Gold Edition

The Speedmaster OMEGA Co-Axial Chronograph featured here has a 44.25 mm case in 18 Ct orange gold and a dramatic black ceramic bezel with a contrasting metallic grey tachymetric scale.  Like all of the gold used in OMEGA’s products, orange gold is 18 Ct, meaning that the metal is composed of 75% gold. It has a high copper content (23.98%) which contributes to its vivid colour.

The remaining 1.02% is divided evenly between platinum and silver. The platinum enhances both the hardness of the material and the value of the precious metal. The fact that platinum doesn’t oxidise acts to stabilize the red colour. This Speedmaster OMEGA Co-Axial Chronograph has a black enamel dial with 18 Ct orange gold transferred elements and hands. It is offered on a black leather strap.

This timepiece is equipped with the OMEGA Co-Axial calibre 9301 and thanks to its Co-Axial escapement and free sprung-balance; the chronograph will deliver outstanding reliability over a long period of time.

The innovative column-wheel chronograph has 12-hour and 60-minute counter hands placed on the same subdial at 3 o’clock. This familiar arrangement of the hands, which recalls the hour and minute hands on the main dial, enables intuitive reading of the chronograph. It also has a central chronograph seconds hand and a small seconds hand on the sub-dial at 9 o’clock.

The two chronograph control pushers function totally independently – accordingly, there is no risk to the chronograph mechanism as a result of inadvertent manipulation.

Like OMEGA’s other in-house Co-Axial movements, the calibre 9300/9301 features a decorative pattern known as “Côtes de Genève in Arabesque”.

It is also equipped with a silicon balance spring. Silicon is non-magnetic so it is not influenced by magnetic fields. This quality combined with the excellent resilient coefficient of silicon allows the balance springs, which are etched on a silicon wafer, to deliver improved chronometric performance. Silicon also has a very low fatigue influence and ages slowly. The outstanding reliability delivered by the combination of Co-Axial technology and the silicon balance spring is such that OMEGA delivers its Co-Axial watches equipped with silicon balance springs with a full four-year warranty.
