I love these straps, they're a bit stiffer than the Swiss Tropic, and the 19/16 taper is exactly the right match to a vintage watch. NOS unused old-stock silver/grey synthetic divers watch strap with current production bead-blasted stainless steel buckle. The buckle measures 16mm inside, I can switch to polished if you prefer. The ends are 19mm (3/4"). Spring bars are included. The length measured end to end excluding the buckle is 7 7/8" (200mm). Shown with a vintage skindiver as an example of fit. $38/shipped quickly & insured in the USA. 58A.25964 Thanks, Scott timesofplenty
