Pretty rare watch.
The Tonneau case is 14K Yellow gold filled throughout and has engraving on the sides. There is a name engraved on the back of the case as shown. A 15 Jewels 3 Adjustments Swiss movement signed Longines Watch.Co. The movement dates this from 1926.
Silver dial but there is some patina on the dial, however it's not too detrimental the numerals are crisp and visible, the case has only barely visible surface scratches but it in very good condition for its age..
Cosmetically speaking overall this watch is in good condition and is running well..
