Lost the clasp for my kenneth cole reaction stainless stell watch

It sounds like you are talking about a watch, but Kenneth Cole don't appear to sell watches. If you bought it from eBay or Amazon, or a market, it is a Chinese watch with their name on it.

Thank you for contacting FixYa,
You can contact Kenneth Cole for a replacement band but I am afraid the band is probably going to be alot more then the $65 for the clasp. I would honestly just replace the clasp unless the band is worn in which case I would do the band.
Sorry.
KC can be reached at 1-800-KEN-COLE

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:
V377
Stainless Steel Caseback
2035 Movement
Base Metal
Bezel
20279knx
A126-06

did you find one? looking for one myself
