A7750 Chrono

[Francisco]

Hi:

It is an A7750 three weeks old. At the very beginning the minute totalizer sometimes shifted two minutes in one minute period. This problem happened around position 2 of the minute totalizer.

I talked to the dealer (Joshua). He told me that after using the chrono for a long period it will improve. "It is like a car".

Now, it is doing the same, but in the position 15 of the minute totalizer.

For example, after 1 hour, the chrono is indicating 64 minutes.

Any help?

Happy New Year

All the running in the world won't change or fix it.

The problem is with the chrono seconds gear minute arm. This little arm sticks out from the seconds gear, and each minute it moves the minute totalizer gear one tooth...yours is not adjusted correctly and moving the minute gear more than one tooth at a time.

It needs to be taken apart and adjusted to fix it.

I wonder what kind of cars he drives??
