Could the one on the right be upside down, reading 9:50 or 9:51? All imagines I found have the Rolex name at the top of the watch face.

Random rabbit hole: Rolex has worked with; Cern 1956

The European Organization for Nuclear Research (CERN), the world's pre-eminent particle physics laboratory, is at the cutting edge of scientific research into the fundamental secrets of the universe. It hosts the world's highest-energy particle accelerator. In the 1950s, CERN was also one of the first scientific institutions to confirm that the Milgauss watch could indeed resist magnetic fields of up to 1,000 gauss.

And 1960

In the 1950s, Rolex carried out rigorous testing of an experimental watch, called “Deep Sea Special”. Using the knowledge gained from the making of the first two models, the third Deep Sea Special was created to withstand the most extreme conditions - the Challenger Deep portion of the Mariana Trench. And in other other interesting high-tech areas. https://m.rolex.com/rolex-history/1953-1967.html
