  • Great poster! Did you know you’ve missed the “g” off the end of Tenzin [sic] Norgay’s name? (And thank you for not saying that Hillary was wearing his Rolex to the top of Everest in 1953: he was wearing a Smiths De Luxe watch. Also thanks for not repeating the lie — it’s not too strong word — put about by Rolex that the Oyster was the world’s first waterproof wristwatch case; it wasn’t, not even nearly.)


    • Thank you for your feedback. Of course I’m aware of the real Mount Everest story. We still need to figure out what Tenzing was wearing on his wrist though. As for the first waterproof watch, I’m aware of the Depollier story but would object that Borgel was first in 1905, which is mentioned in the timeline.


  • Very interesting interview with a lot of background knowledge and nice anecdotes. Congratulations, José and Rico! Highly recommended 👍🏻
