This is a nice and original collectors item from the 70ies. Tag Heuer was for centuries the official timekeeper of the Formula 1. So they did a collection of small replica Helmets from the famous Drivers of these times including a quartz clock inside. This model was inspired from the Suisse Champion Jo Siffert.
This unique time piece is in a good condition, but the clock is not working.
It comes along with his original paper box.
