In fact Jean Jacques Fiechter (Blancpain) & René Paul Jeanneret (Rolex) were both member of the Club Alpin Sous-Marin in Cannes France (1953)
Don't forget

Indeed, Apollo 13 CMP Jack Swigert wore a NASA-issued Omega Speedmaster 105.012-66 (NASA n° 69) over his space suit but also wore his personal Rolex GMT-master Pepsi 1675 pilot watch underneath the space suit. He was the first to wear a Rolex to the Moon, but it was later also done on Apollo 14 ( Mitchell and Roosa wore a GMT-master ) and on Apollo 17 ( Ron Evans carried a GMT-master in his PPK).
April 16, 1970 : Jack Swigert timed the 14 seconds LM DPS burn ( Lunar Module – Descent Propulsion System) using James Lovell’s Speedmaster as they knew it was the most recent serviced chronograph!
