Tank-style wristwatch bearing the name 'Paul Vallette'

This appears to be a vintage rectangular 'tank' style wristwatch with a dual-dial configuration. The case is gold-toned, likely gold-filled or plated based on visible wear, featuring decorative vertical ribbing along the flanks consistent with Art Deco design influences from the mid-20th century. The light-colored dial bears a printed signature reading 'PAUL VALLETTE' within the upper register. The watch features two distinct tracks: a larger primary dial for hours/minutes and a smaller secondary register below it, commonly used for tracking a second time zone or as a prominent sub-seconds dial. The hands appear to be a dark-finished baton or leaf shape. The watch is presented on a gold-toned expansion-style metal band. Visible condition issues include surface scratches on the crystal, pitting or oxidation marks on the dial plate, and significant brassing (wear through the gold plating) on the lugs and case edges. These wear patterns are consistent with an age dating to approximately the 1930s-1950s. While the dial branding is clear, this identification remains a hypothesis as internal movement inspection would be required to verify the maker and movement quality. The overall craftsmanship suggests a mid-tier commercial timekeeper of its era.

Based on the image provided, I have examined this vintage rectangular wristwatch bearing the 'Paul Vallette' name. The piece exhibits Art Deco design characteristics consistent with 1930s-1950s production, including a ribbed gold-toned case and a dual-dial 'doctor' or 'duo' layout. From what I can see, the case shows significant brassing and wear-through on the lugs, suggesting a gold-filled or plated composition rather than solid gold. The dial displays age-related spotting and oxidation. My value estimate is based on the hypothesis that the internal movement is of mid-tier Swiss or American quality consistent with the dial signature. I cannot verify the movement's caliber, condition, or manufacturer from a photograph; a physical inspection by a watchmaker is required to confirm the movement's integrity and the metal content of the case. The market for mid-century 'tank' style watches remains steady due to their classic aesthetic, though value is heavily suppressed by the visible condition issues and the lack of a prominent luxury maker name. The estimate assumes the attribution indicated by the dial signature is accurate; should the watch be found to have a generic or replacement movement, or if the case is a later reproduction, the value would likely fall to $50 or less. To confirm this appraisal, an in-person examination of the movement and a verification of the case hallmarks are necessary. The current estimate reflects its status as a vintage fashion piece of assumed mid-tier origin.
