it definitely should, but these very nice watches, manufactured by Charles Gigandet, imported to the US by Wakmann and sold under Gigandet, Wakmann and Vulcain branding have been called "Breitling Datora" by so many ebay sellers, that we became used to this.
I have never seen this watch with the Breitling branding, nor have I ever seen pics, ads or catalogoues where it was called a "Datora". Am a bit suprised by some of the other claims in that listing, including the claim that these watches were "reputed to be manufactured by Breitling", considering the seller is Bill Shaine, well respected Breitling collector and trader.
Thanks for the update Fred and am sure the watch by itself is nice and a Wakmann. However I think using Breitlings name in the listing would unfairly mislead a prospective buyer to bid higher thinking was a Breitling manufactured Datora. Also not sure why the term "military" is used. I usually browse Bills listings because he is highly recommended and a Breitling collector and has some interesting Breitlings on sale but am quite surprised too with that misleading listing considering even a newbie like me had an inkling that it wasn't a Breitling.
