Abercrombie Fitch shipmate movement ID help

[cduke]

Hello all,

I need to find parts for this military watch from Abercrombie & Fitch from the 40’s. I don’t think it is an Heuer movement but was wondering if anyone could help ID it. I looked on Ranfft site but could not tell how to begin a search. Thanks for the help.  Ps it has a sundial for seconds in lower center.

First I was thinking of a FHF then I changed my mind and will go with a The General Watch Co - Helvetia, Helvetia 81.
If you can get a shot so one can see the keyless I think it will be easier to identify....

I'd concur with @HSL making this specifically a Helvetia 81-24.

Hello all,

Thanks for the link to my site.

To really find out about these watches and all the innovations in them have a look at my page on shock and water protected watches:

https://www.helvetiahistory.co.uk/1930s-sports-watches

The Abercrombie and Fitch watches are under the 'other brand names' at the bottom. Including a picture of your watch I believe from when it was on eBay.

These watches were developed and completely manufactured by Helvetia, incorporating more water and shock proof features over the years, though sometimes sold under other names e.g. Huber and Aero.

Thanks.
