And it’s the Chronoscope which has kept that on the bezel, and just returned all the other ones to the dial in an intersecting expanse of small time-interval measuring tools, hence the name. In terms of the movement, this watch is no more or no less complicated than any other chronograph but for a few things. In order to keep this design from becoming utterly unwieldy, Omega utilized a manual winding movement – the Co-Axial caliber 9908. The manual nature allows for the thickness to be minimized. It also allows for a fun little quirk. While this watch appears to be a twin register chrono, it is actually a three register in practice. At three o’clock there are, in fact, two hands operating the chronograph minutes and hours. I think this watch would be entirely unusable with a third subdial, so hats off to Omega for that.
