Vintage Hirsch Leather Watch Band Strap White New Old Stock 17mm in Plastic Case. The ends measure about 11/16" wide each. This is an exact match for a red leather version I also have that was marked as a 17. The band has 1 dark line from age and how it was packed I assume. Otherwise fine condition. The insert card became lost but I guarantee this is new old stock and a size 17mm - see detailed photos.
