An odd one for me. A smaller men's watch from the 30s I believe.
Not to bad under the crystal. The second hand was lose but was easy to put back.
This actually surprised me. The case is made of thick stainless steal so it must have been a expensive watch in the day.
The movement has chock protection of some kind but first time I have seen this one.
I found a similar Helvetia on the bay but they are asking silly money for it but then maybe I should as well so give me $300 and it could be yours...
