Notes: Manual calibers accuracy changes as the mainspring unwinds. Because the 11C5 has a massive 100-hour reserve from a dual-barrel setup, the delivery of torque is highly linear for the first 3 days. Expect optimal precision (+1 to +2 seconds) when kept wound above 30% on the dial's power reserve indicator
