It's a beautiful watch and works very well.
I got it from an overseas collector.
It is a watch that can be used widely for casual to business scenes.

Arm circumference: about 14cm

About 4 minutes/day with Timegrapher measurement (app)

Maintenance and care
Set the time and wind the watch before wearing it on your wrist. This prevents side pressure if you wind it on hand.
Clean your watch (except leather straps) regularly with a soft cloth.
Do not expose your watch to extreme temperature changes, moisture, direct sunlight, or strong magnetic fields.
Please read the entire description above carefully before purchasing. Please read the above description and purchase if you are satisfied.

In addition, there are small scratches that cannot be shown in the photos, please buy only if you understand these points.
This is an old watch, so please refrain from buying it if you are looking for perfection.

It would be nice to find someone who can use it carefully.
We wait for the next owner who would take it with good care.
