The Speedmaster OMEGA Co-Axial Chronograph

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.

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 first in-house Co-Axial chronograph

The OMEGA Co-Axial calibre 9300 is the dramatic next step in the revolution in mechanical watchmaking that started in 1999 with OMEGA’s launch of the Co-Axial escapement.  Not only does the new movement deliver superb timekeeping performance, it is the first of OMEGA’s exclusive in-house Co-Axial calibres to incorporate a chronograph function.

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.
