The Speedmaster OMEGA
Co-Axial Chronograph:
enhancing a legacy

Since it was launched more than half a century ago, the OMEGA Speedmaster has defined the classic chronograph. It is rugged and reliable and has a timeless design. And since the day in July 1969 that it was first worn on the lunar surface, it has been known by its nickname, the Moonwatch. The Speedmaster OMEGA Co-Axial Chronograph dramatically reinterprets the world’s favourite chronograph.

No chronograph will ever match the OMEGA Speedmaster Professional’s legacy of adventure. It has been a regular space traveller for nearly half a century and was a part of all six Apollo lunar landings.

But an innovative new member of the family – the Speedmaster OMEGA Co-Axial Chronograph – is set to establish its own reputation. Equipped with the OMEGA Co-Axial calibre 9300, it shares some core elements with the original Speedmaster Professional – the black dial, the Moonwatch-style hands and the familiar black tachymeter on the bezel. It also has some distinguishing features that will attract an even wider audience to the world’s favourite chronograph.

“It has distinguishing features that will attract

favourite chronograph.”

The Speedmaster OMEGA Co-Axial Chronograph has a 44.25 mm case in the classic stainless steel that has always been associated with the Speedmaster Professional. This model has a bevelled black dial with white transferred elements and varnished white hands. It is offered on a black leather strap or a stainless steel bracelet.

In addition to the stainless steel OMEGA Speedmaster Co-Axial Chronograph, a version has been produced with a platinum case and a black leather strap. Another features an unusual 18 Ct orange gold case, also presented on a black strap. These precious metal editions are powered by the OMEGA Co-Axial calibre 9301 with a luxury finish including an 18 Ct red gold rotor and balance bridge.

Only two sub-dials

The dial has two sub-dials instead of the three normally associated with Speedmaster. This is made possible by the innovative placement of the 12-hour and 60-minute counters in the same sub-dial at 3 o’clock allowing a comfortable and intuitive chronograph reading.

The Speedmaster OMEGA Co-Axial Chronograph's elegant, slim body is the result of a unique design concept: it has a box-form scratch-resistant sapphire crystal not only on the front of the watch but also on the polished screw-in caseback. The latter, with anti-reflective treatment, reveals perfectly the beauty of the movement.

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

A silicon balance spring and a four-year warranty

The Speedmaster Co-Axial Chronograph 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.

The Speedmaster OMEGA Co-Axial Chronograph is a welcome addition to the great Speedmaster family. With its choice of case metals, its innovative movement and its legendary family name, it will find an enthusiastic following among Speedmaster fans who want to combine the impressive legacy of an iconic chronograph with the best series-produced mechanical watch movement in the world.
