These watches were likely what was later just simply marked with the 'Pan American' stamp on the case back. Otherwise there is not a discernible difference between these plain backs and Pan Ams. Case back is otherwise correctly hallmarked for Gruen. Dates to early 1945 on serial numbers from the movement.

So... Early Pan American styled watch in chromed basemetal bezel with stainless steel (Guildite) back.
Movement has been overhauled, including restaffing the balance, and a new white allow mainspring. Runs with good amplitude and low error.

Dial shows some minor loss on the details in the seconds track and the hands show signs of exposure to moisture. To be upfront the movement was pretty rusty but cleaned up well and what couldn't be cleaned was replaced. Specifically the setting bits and the ratchet wheel.

$200 + shipping.

More pictures on request.
