Overhaul

What is overhaul? How often does it need?

Watch movements need to be maintained regularly, even if they are working well.
The period depends on the situation. How often do you wear it or the watch has a waterproof case? However, it is generally recommended to do it every 3 to 4 years.
If your watch has not been done anything in recent 3 years, it is time for checking.

We would like to introduce the process of an overhaul of a watch movement.

The movement is checked with disassembling everything.
If we find something needs to be extra cost, we will inform you immediately. If you would like to cancel the overhaul service, we won’t charge any cancellation fee in this timing.


General repairs and adjustments are included in the overhaul service.
On the picture, it was adjusting cannon pinion because the hand-winding was too tight.


After checking and disassembly, all movement parts were cleaned by hand to remove any major dirt.


Then, clean them with the machine.


Assembling with check again and lubricate at proper place and amount.


Adjusting the rate of accuracy.
We aim to adjust within +10 seconds per day for lever escapement movements.


The case is also checked and cleaned during the movement cleaning process. (enamel or painting case can’t be cleaned with ultrasonic machine. In that case, we clean it by hand as much as possible).
Please check the ultrasonic cleaning here.

We are specialized in movement service, so we don’t provide case polishing service.
If you would like to have case polishing service, we introduce you to the appropriate workshop.


Attaching the dial and hands to the cleaned movement and put it back in the case.


After that, we check and adjust the accuracy every day for around 2 weeks.


Please note that;
* Replica or fake watches are not accepted.
* Large deck clocks and wall clocks are not accepted.
* Partial repairs, or without a full overhaul, are not offered.
* Modification works (e.g. swapping hands, dial or a movement part) are not offered.

Thank you for understanding.
