Original Tochigi Cowhide (Japanese Vegetable Tanned Leather in Tochigi prefecture) made for and market by HDT Design. Perfect strap for your larger vintage chronograph watches with 22mm lugs. The case underlay is 50mm wide. It has been mounted one time which left a little scuff to the top, easy to mask with some leather polish but I want to show what I sell. These are still being sold for 70 USD, so I am offering this for half price. More straps and accessories at www.sometimeago.com.
