An unexpected fact has been discovered!!

All of the products we handle have been overhauled.
At that time, it is natural to replace consumable parts.
In particular, mechanical ``mainspring'' replacements are common regardless of brand.
Depending on the machine, parts may not be made, so
It can also be used from other machines.

However, sometimes parts material stores may have the parts you are looking for in stock.
Sometimes I hear some unexpected stories...

"Seiko's 45 series springs are made in Switzerland"




This is the most surprising story I've heard recently.

The mainspring is the battery in a battery-powered watch.
As it is the most frequently used part, wear and tear is also high.
In particular, the mainspring with a high rotation movement called high beat,
They often need to be replaced approximately once every 10 years.

Even if you are lucky and don't need to replace it on the spot,
It's a part that will have to be replaced eventually.
If parts are not available or cannot be arranged at that time,
Even if you arrange other movements, the mainspring cannot be used, etc.
There may be various reasons.

Especially when it comes to Seiko 45 series moves,
Hand-wound high beat movements such as 45GS and 45KS.
A masterpiece among masterpieces that pioneered the high-beat movement into a practical product.
This machine not only has a mainspring, but
The part called the barrel is also heavily worn.
The recoil when the mainspring breaks can damage the gears.
In fact, it can be a troublesome watch.

So when I repaired the 45GS I sold the other day,
I heard about this from a material store,
``It was the first time I learned that the mainspring was made in Switzerland even though it was produced in-house in Japan.''
I was talking about this with a craftsman.
I thought all the parts were made in Japan, but
How difficult was it to go high beat back then?
And not only in Japan but also in Switzerland, we manufacture high-beat movements.
I can see that it played a role.

Old watches have already been sold
Even though years and decades have passed,
Every year something comes up that I don't know.
This is how you learn information you didn't know.
By receiving and disseminating information from every possible direction,
It can be delivered to many people,
This may be the fun of dealing with such "vintage items."

By the way, the parts I got this time do not have the Seiko logo on them,
They seem to source their products from the same manufacturing plant.
However, it seems that this part is hardly manufactured anymore.
I bought the remaining stock in bulk.
The price is...even though it's for Seiko, it's more expensive than Rolex!

The reason why you should still get it is simple,
We keep these parts in stock for customers we have sold to in the past.
Customers will be in trouble if they don't have parts in case of an emergency.

So this time I have a little surprising story.
Maybe someone in the know knows,
At that time, please keep this story in your heart!
