NOS unused 1960s-1970s old-stock synthetic translucent blue watch strap with original & current production stainless steel buckle. Some people prefer the new buckle to the original as it's a bit thicker. The buckle measures 16mm inside. The ends are 18mm. Spring bars & tool are included. The length measured end to end excluding the buckle is 7 3/8" (187mm). Shown with a vintage Benrus Ultra Deep Cuper Compressor watch as an example of fit. 19D.9920 $36/shipped in the USA, paypal or venmo Thanks, Scott
