HANDS Original


Ref. 6238 sans-tritium Rolex offered their earlier chronograph and triple-calendar watches with both luminous and non-luminous options, however by the 1960's luminous dials and hands became standard on steel chronograph models. Close examination of the dial reveals no luminous was applied at the factory. The dial is still signed T SWISS T, indicating the use of tritium, in the same manner the laterproduced CERN dial Milgauss was similarly stamped, although no tritium was present. Although the variation is minor, the visual difference is quite signifi cant, providing the wearer with a cleaner, more elegant dial.
