We 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 is 16mm inside, we can switch to polished for no extra charge. The ends are 19mm (3/4"). Spring bars are included. The length end to end excluding the buckle is 7 7/8" (200mm). We've shown it with a watch so you can see how it works & looks when installed, watch not included. 58A.25694
