Collector Notes & Dating

This 85-year old Wyler Superior Tank features a patented “Clamshell” waterproof case designed by Taubert Borgel in the 1930s. This was one of the first truly water-resistant designs for rectangular dress watches and is stamped BREV.DEM. Is the French abbreviation for brevet demandé—“patent pending.” Swiss makers stamped it in the 1930s–40s to show a design was filed but not yet granted; after approval you’ll often see BREV. DEP. or BREVETÉ with a patent number. Dial typography, four-screw steel case stamped “Acier Inoxydable,” and overall design place this in the 1940s. Caseback no. 66426 is a case code. Period-correct features and printing align with Wyler’s mid-century “Superior” line.
