NOS unused 1960s-1970s old-stock white tropical rally dive watch strap with both original and new heavier-duty stainless steel buckle. The buckles measure 16mm inside, some people prefer the beefier buckle so we've included both. Graduated holes, perforations, and basket weave texture. The ends are 3/4" (19mm). Spring bars are included. The length measured end to end without measuring the buckle is 7 3/4" (196mm). Shown with some vintage diver watches as an example of fit. 30.8160. We have a few of these. $18.95 shipped insured in the USA. Thanks! Scott
