Here is a stunning vintage Speidel Twist-O-Flex watchband from the 1960s and 70s, LONG, manufactured in the US and in its original packaging. Named "Valencia", the watchband is a high quality "Expansion" type (stretchy) with 10K Yellow Gold Filled top caps and Stainless Steel caps on the underside. In the old tv ads it was twisted back and forth to show its flexibility (I remember them!) It is New Old Stock in its original box with its manufacturer's tags, and is marked "Long".  Back in the day Speidel was sold only in Jewelry Stores, a mark of their quality. This is such a classic midcentury design--fabulous! Please read everything, see photos and let me know if you have questions. Thank you.
