Swiss Made vintage early ladies watchband buckle. Stamped INOX on the back, which is the French abbreviation for Acier Inoxydable or Stainless Steel. Very nice touch on a special band to have a quality silver-colored buckle like this. Great way to finish off your white gold or stainless steel vintage watch. Great early vintage watch styling to this buckle, with sharp angles and a nice polished surface. Very elegant. Difficult item to find New Old Stock like this in this size in stainless steel. This is an NOS watch vintage 9mm wide inner opening watchband buckle from around the 1960s/70s. Often these fit straps with 9mm 10mm 11mm 12mm or 13mm lug end sizes. Top to bottom clearance through the buckle is just 6.8mm so this will only work with flat or unpadded style straps, not newly made padded thicker bands. Plenty of vintage NOS watchbands listed in my EBAY store Squinky will take this buckle including many exotic skin bands I have listed. Great for a vintage white gold windup antique watch model. Buy with confidence: I have earned more than 13,000 positive feedbacks on EBAY since 1998 and have been a member of the NAWCC watch collector's association since 1997.
