I can't help with value but it appears that the underside of the band is maked "U.S.A" so the band may not be original which could effect its value. Good looking watch! A good watch dealer should be able to recognize the maker who probably was contracted by H&H to produce this accessory item.. Just saw a H&H edition Range Rover listed on Bring a Trailer not too long ago.. Maybe of same era.. early 90's??
