The 6105 is where the Datejust finally gets its name. The concept had existed since 1945 — the 4467 invented it, the 5028 omitted it, the 5030, 5031, 6030, 6031, 6074, and 6075 iterated on it — but through all of that the dials said “Oyster Perpetual” and nothing more. An owner of a 1946 Datejust owned a Datejust only by catalog reference; the watch itself did not say so. The 6105 ends that. Introduced at the turn of the 1950s in the same 36mm Big Bubbleback case the Ovettone family had been using for five years, it is the first Rolex reference to print ''Datejust'' on the dial. Everything else about the watch — the gradual date change, the reeded bezel, the gold-only bias, the domed caseback — is inherited from its predecessors. What is new is the word.
