I've come across this Ingersoll and am struggling.
It is in a backless case - the only access is via the front glass. I have pulled the crown as hard as I am willing and this does not separate.
The watch winds, ticks and stops, so I'd like to get a look at the mechanism. Can anyone help?
Also, the only Ingersolls I've come-across are Triumphs, this is not so marked. Can anyone help with a model or age?
Thank you all!
