Post z autorstwa Jim Ki Kai z Rolex collectors world. Pomyślałem, że udostępnię, bo ciekawa sztuka. "The “END GAME” Just LANDED ~ my ultimate acquisition this year I would say ~ the mother of all ROLEX Submariners, the “SUB-AQUA” 6204! High-radium, pencil hand set, 38mm case w/ unique 5.3mm crown , specific 42,xxx serial range, early no hash alloy insert, calibre A260 movement, 100 meters depth and what’s else you wanna know?! Some said the name “SUB-AQUA” was so similar to a pre-registered UK diving club named “British Sub Aqua Club BSAC” during the same period of 1954, so ROLEX used “SUBMARINER” instead + later signature Mercedes Hands for all subsequent diving model references! Only 4-5pcs known and here is one of the very few with surface! "
