Alain Delon, Lino Ventura and Sergio Reggiani all wore at least at one point in the movie the superbly looking Sherpa Ultradive dive watches, in many cases for diving purposes, yet also casually during other activities. This was maybe the first time that a watch was so intensely featured in a movie, even before Steve McQueen and his Heuer Monaco in „Le Mans“. How the three Ultradive models ended up in „Les Aventuriers“ unfortunately remains a mystery.
Alain Delon continued to wear the watch, as he apparently grew fond of it, and wore it on many occasions, to be seen on several photographs with his wife, family and friends. He features the watch in another movie, „Adieu l’ami“ with Charles Bronson and wears it on the set of „Swimming Pool“ next to Romy Schneider (yet not in the movie).
