I hope this is the right place to ask this.
I'm just trying to find out when Swiss pocket watches finally went keyless.
The reason I'm asking is that I've owned a Swiss pocket watch for some years. This watch has no signature anywhere, not on the dial or movement that can be seen. I can place the age to between 1887 and 1907 because it has the 3 bears & 0.935 silver hallmarks for export to England.
I'm just hoping to get closer to it's age.
Here's a picture.
