I have an old (possible Breitling) chronograph, marked Kronometer Stockholm. I want to have it functional again.
So I need a new/old button:
As you can see one of the push buttons(it is probably called something different, but my watch terminology is close to non-existing) is missing.
My friend the watch maker told me it had to be the following measurements:
Outer diameter: 3,8 mm
Tread 0.9 mm
Inner diameter 2 mm
Height 2 mm
Can anyone help me, or point me to where I could get hold of one?
I would be very grateful.
