Mike:

Are you referring to the chronometer function or the chronograph?

A "chronometer" is a "label given to a watch which has undergone precision tests and received a certificate from an official body (COSC)". That is the quote right off the Omega website. If a watch receives the "chronometer" rating that means that it is extremely accurate - an important function when measuring small fractions of a second.

On the other hand, the "chronograph" is used by simply pushing on the top button on the right side of the case to start and stop the chronograph. To reset the chronograph, you press the bottom button.

Omega defines a chronograph watch as "complicated watch with a function for measuring short time periods in addition to its function for permanently displaying hours, minutes and seconds." And by "complicated", they don't mean confusing! They simply mean that the movement includes other mechanisms - thus making the movement more "complicated".

By the way, not all Speedmaster watches have the chronometer rating. The Racing model, pictured above, is actually called the "Legend" and it does in fact have the Chronograph rating.

Hope that helps. Take care.
