The power reserve for 9SC5 is with the chronograph running. The power reserve without the chronograph running will differ.
Caution: Depending on conditions of use (such as normal usage time, temperature environment, and winding state), accuracy may exceed the abovementioned range. Therefore, for normal usage accuracy when it is actually used, -1 to +8 seconds per day is specified as target values.
The specifications are subject to change without prior notice due to product improvement.
