As I know this one was on strap "only" unfortunetally original buckle from 197x is not part of watches.
But I have new one and also NSA bracelet.
this bring question if you will wear it on strap or bracelet? Strap will have Heuer buckle and it will be like original.
Stepan.
P.S. I like Autavia more than Carrera, so this Verona shape is not exactly my favorite, but it was for very nice price.
And if I will choose some other watches than Heuer it will be Zenith El primero TV shape, blue colour (similar to Silverstone)
