Ive seen these before, mentioned as 60's Carrera boxes without the step and prong though.. Here's some links from few years ago... Post your watch with it next time =P
: Does anybody know at what time Heuer sold watches with this kind of
: box? Few years ago I received the box together with my Carrera
: 1153 from 1970. But I doubt that this is the original box.
: Thank you for your information.
