The shape of the wheel looks like an hour glass with inlaid gold added for weight. Two other parts also using this new material are the Pulsomax escapement and the Spiromax balance spring. The combination of these three components involved in the energy transfer of the watch are together called “Oscillomax.” The caliber 240 Q Si is based on the existing ultra-thin perpetual calendar caliber 240 Q automatic movement.
