Notes:This is a "meca-quartz" watch in that it needs a battery and is regulated by a quartz oscillator, but it has a mechanical chronograph function. As a result, the chronograph seconds hand has a smooth, sweep movement, and snaps back immediately when reset. This movement is similar to cal. 8T63 but with a stopwatch hour hand instead of a 24-hour hand.
