Mean daily rate*:
A mean value of daily rates in a condition where the movement before assembly in a case are measured in 6 positions in a fixed manner under artificially controlled environment for 17 days.
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 +10 seconds (-1 to +8 seconds for Cal. 9S86 and 9S85, –5 to +10 seconds for Cal. 9S27) per day are specified as target values.
The specifications are subject to change without prior notice due to product improvement.
