Nice watch, however, I don’t believe it is representative of Art Deco. There have been a lot of posts to this thread which incorporate similar “graphic” design elements as the etching on the case of the watch you shared, the font used on the numerals, etc.. I believe these design elements are more representative of the Arts and Crafts movement, which was also popular during this period. Art Deco is perhaps better known to most people than Arts and Crafts and, as such, gets associated with items from the period.
