I wanted to try a British Jaeger

[YCymro]

I believe Jaeger made a smaller 4” version which might suit you better. Scrap yards were full of them in the 70s, along with Smiths, Veglia Borletti etc etc.

You may find one to suit your wrist here:

Or here, if you don’t mind used

Acceptable overhang.
