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 19mm. Spring bars are included. 75/120, the length measured end to end excluding the buckle is 7 3/4" (195mm). Shown with some vintage diver watches as an example of appearance, watches are not included. 30.8160 $18/shipped in the USA. Thanks, Scott
