Very rare vintage 1960s APOLLO Swiss rally / diver rubber watch strap – 22 mm.
These straps were widely used by the watch manufacturers back in the 1960s – 70s for their top rally or diver watches.
The “B” mark on the back of the Heuer buckle certifies the authenticity (the mark is centered and truly engraved, not scratched like in other eBay listings which claim to sell authentic Heuer buckles for up to $30).
Both strap and buckle are genuine products, very hard to be found elsewhere in this condition. Perfect match for a Heuer Camaro or Carrera.
