Rolex must have considered Ref. 5440 to be the exemplar of the series because it is the one featured most frequently in contemporary advertisements and press coverage. Perhaps this did the line a disservice, as yellow gold was going out of style at the time, and this model is most likely to say “grandpa’s watch” to a younger buyer. Still, if you want a Cellini Prince, Ref. 5440 is probably the most iconic.
