An interesting attempt at water resistance, the bayonet bezel rotates and locks into place. Two piece split stem, and regular water resistant crown with gasket. I won't be undertaking the restoration of this one til I get some more time, but I thought it interesting enough to post so we can all get a look at it.
Stamped 'N0' on the movt, but 'M0' inside the case, and this is an indication of a much later movt being placed in this watch. The depth of the case is insufficient to allow for an automatic movt, so the one that is present, the 11AFC, handwinding, is probably close to being correct. Swiss made case, and dial made by Durig Freres of Bienne.
A typical hazard for this series was the shearing off of the dial feet, when rotating the bezel to remove it for service. This has happened here, and we will be laser welding the feet back on, and while we're at it, will be refinishing the dial.
The watch is from a Montana Watchmaker's estate.
