Repair of a product that was brought in by a customer the other day.
This time, we were told that the watch could be wound indefinitely even by winding the crown, so we overhauled it and replaced the mainspring.
In a hand-wound watch, the mainspring is the most active part, similar to the battery in a battery-powered watch.
With use, parts will wear out.
This time, it seems that it hadn't been overhauled for a long time,
This work was carried out together with a spring replacement.
This is a part that we often use in our shop, so the work was relatively easy.
Parts prices have risen sharply recently, so we would appreciate it if you could request repairs on a regular basis.
This time it was brought in for repair
Overhaul ¥33,000
Mainspring replacement ¥8,800
Total: 41,800 yen
It is well known that hand-wound and automatic watches are powered by mainsprings.
In the case of old watches, the mainspring is made of a thin metal, so it is a part that will eventually break due to metal fatigue.
It seems that recent watches use silicon for their mainsprings.
Silicone doesn't cut, but it does break, so replacement costs are high.
Considering these points, regular maintenance is important regardless of the model year.
To avoid major repairs, be sure to request regular maintenance!
