В. ГАБЮ / W. GABUS

The Moscow house signed its work in both Cyrillic and Latin — В. ГАБЮ and W. Gabus. These forms are documented on the Held trench watch, a First World War officer’s wristwatch, and an Imperial Russian pocket watch, all signed В. ГАБЮ, as well as on the double-signed gold hunter marked W. Gabus. The trench watch additionally carries period hallmarks.

Gabus-Guinand

The Les Brenets workshop registered nine Swiss trademarks across four original filing dates between 1887 and 1897, and renewed one of them in January 1908. Surviving casebacks can carry the workshop name and technical specifications; some also bear Russian silver hallmarks.
