NOS unused old-stock 1960s black divers watch strap with original and current production stainless steel buckles. I include a thicker current production buckle because some people prefer it. I've had lots of Hong Kong tropics and these are by far the best. Supple & flexible, the basketweave is deep, and the casting details are crisp and sharp. The buckles are 16mm inside. The ends are straight 20mm. Spring bars are included. 72/128, the length end to end excluding the buckle is 7 7/8" (200mm). I've shown with an Aquastar 63 so you can see how it works & looks when installed, watch not included. $60/shipped with tracking & insurance. paypal & venmo Thank, Scott vintagewatchbands.com
