ETA 2893-2 automatic is gaining 10 seconds a day after 2 months. Started off at 5 seconds per day. Is 10 seconds acceptable for this movement.

Thanks......

According to TAG Heuer's website:
http://customer-service.tagheuer.com/en-us/question/what-is-an-automatic-movement-0
Why does my automatic watch not keep accurate time?
The accuracy of TAG Heuer watches depends on several factors, including the type of movement and conditions of use. The following list shows TAG Heuer average tolerance given by the Swiss movement suppliers (based on normal conditions, and full power reserve for automatics):

Quartz movement: between -1 and +11 seconds per month
Standard automatic: between -5 and +20 seconds per day
Chronometer: between -4 and +6 seconds per day
A TAG Heuer watchmaker can carry out a maintenance service to adjust the timing rate of an automatic movement if it is performing outside these tolerances.

If it bothers you I would take the watch in to be inspected. Yes, +10 seconds may be within the acceptable range, but it is on the high side.
