First I want to say that these watches were sort of commissioned by the members of KISS. Yvan Arpa of Artya was contacted by Gene Simmons who said that he liked his work and wanted to have Artya make special watches for KISS. So Arpa flew out to LA to spend time with the band members, talk watches, and voila! Artya watches uniquely made for KISS (and available as piece unique models for you).
I would really like to know more about what Yvan Arpa did with Gene Simmons for a week. I tried to ask him but didn't get much information. Apparently they liked the result. Right now there are three watches. Each are in 47mm wide Artya "deconstructed" cases. The first one features Gene Simmons, then another with Paul Stanley, and the last one has a KISS guitar pick and guitar string in the dial - that were actually used by Paul Stanley. Interesting use of a guitar pick in a watch I must say. These look a bit spooky and surreal... which is probably exactly what the KISS folk wanted.
While it is unclear exactly how many of these KISS watches are going to be made, they are each all unique and available on Artya's website here. Price is between 3,800 - 6,900 Swiss Francs each.
