Leather watch band
I might have the solution. Is it a rectangular watch with a leather strap? It sounds weird, but I have a watch with no brand name on it (bought yesterday from K-Mart at $9.99) with the model #A126-06. The package insert said "Advance Watch Group." I googled them, and they manufacture watches for Kenneth Cole, Tommy Bahama and a bunch of other designers.
I was really surprised because K-Mart is the last place I'd buy a watch, except that it looked like my broken Raymond Weil tank watch.
I suggest you go to K-Mart and see if you find a watch that looks like yours.
The back of this watch is marked as follows:
Stainless Steel Caseback
