Periodic overhaul requested by the customer.
It's been 6 years since I bought it, so I've taken good care of it.
Sometimes I get asked, "Does it need an overhaul?"
Let me explain what an overhaul is for a watch.
In conclusion, "an overhaul is necessary!"
A clock has parts such as gears and jewels built into a mechanical plate and fastened with screws.
Roughly speaking, the structure is like this,
Since "machine oil" is put between the gears and stones,
If this dries, it will not work properly.
Of course, anyone knows that if it is a battery-powered one, it is necessary to replace the battery.
Even if you replace the battery when the machine oil is dry, it may work temporarily.
It will not work properly before long,
Sometimes the clock itself doesn't even move.
So the battery is not the only culprit.
It depends on how you use it, but the machine oil dries up about 5 years after purchase.
Even if you replace the battery, it may not work properly.
Some products can last for more than 10 years with just battery replacement.
It's a bit troublesome that there are some things I can't generalize about (lol)
However, the day will come when battery-powered watches will no longer work properly.
Even though I just replaced the battery, the time keeps going wrong.
In such a case, if you overhaul it, most things will be fixed and it will start working normally again.
If you have a watch that does not work even after replacing the battery,
Please consider overhauling!
