We recently repaired a customer's watch.
This time, the request was for a battery replacement, but since it was not working properly, we performed an overhaul.

Battery-powered watches will stop working properly if the batteries are replaced several times.
An overhaul will be required.
Depending on the individual product and usage conditions, the product may not function properly after the first battery replacement.
You will need to be careful when using the product around water, humidity, and strong magnetic fields on a daily basis.
Although battery-powered watches are easier to use than mechanical watches,
They may be handled roughly during use and storage,
For better or worse, it often still works fine.
If possible, since watches are all precision instruments,
I would like you to treat it with care without getting too nervous.
And when the battery runs out, replace it as soon as possible.
Just a little bit of care will help you avoid the worst-case scenario.
Any watch can be used for a long time.
Of course, if something does happen, we will be happy to help!
