there are loads of VINTAGE period correct aftermarket Stainless Steel bracelets floating around any of which would have been sold in a Jeweler/watch makers shop back in the day ... which would have been appropriate for use on these watches ... JB Champion, STELUX etc etc ..... do not be pigeon holed with must have BULOVA LOGO .. there are loads of vintage ACCUTRON, and CARAVELLE bracelets that shopper would have had the jeweler/watchmaker pair with the watch and even vintage 18mm Omega bracelets ... if u pay attention old omega bracelets they had a pyramid with the omega logo inside it , ... guess who made the bracelet originally for the US watch market [ when european bracelets would have been charged additional import taxes ] ... JB Champion USA [notice the pyramid and JB stamped inside it ]
