Technical description

(1) 22K Gold rotor with uni-directional winding
(2) Large capacity mainspring barrel
(3) Precision-adjustment weights
(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.
