This watch does not use the [[PP 240|Cal. 240 micro-rotor movement]] as it might first appear. Rather, it uses an all-new [[micro-rotor]] movement, [[PP 31-260|Cal. 31-260 REG QA]]. Measuring just 5.08 mm thick, the movement contains 313 parts and 29 jewels. Being an Advanced Research product, it includes the Pulsomax escapement, [[Gyromax]] balance, and Spiromax hairspring though not the GyromaxSi balance. Unusually, the movement runs 10% faster than Cal. 240 at 3.2 Hz or 23,040 A/h.
