Serial Number 383506 was reported as inaccurate.

Note: This Hamilton states it’s an open face but the
one I have winds at the 3 position so is more made
for a hunter case ?

Curator Response: Thanks for the report. There are several verified observations from this run indicating an open face movement. It is possible that your watch is fitted with a conversion dial. Feel free to upload images for further evaluation and documenation.
