Original 1970’s rubber strap from Germany by Eulux (still making straps today). It is a tropic style bracelet in a silver-grey color with holes, New Old Stock – NOS – never worn. It measures 18mm with straight ends at the lugs, then it is a little wider (24mm) and tapers back to stainless steel buckle (16mm on the inside). When fastened in the longest position it measures 18cm from lug to lug so just ad your watch size and you know the total length it will cover.
