NOS unused old-stock 1970s out of production black diver watch band with original and current production stainless steel buckle. The buckles measure 16mm inside, we include both because the new ones are sturdier. The ends are 18mm, flared to 21mm. Spring bars are included. The length end to end excluding the buckle is 7 1/2" (190mm). I've shown it with a watch so you can see how it works & looks when installed, watch not included. 19.5014 $19/shipped tracked & insured in the USA. DM for international. Thanks, Scott
