<small>Datejust → '''6105'''</small>

The 6105 is where the Datejust finally gets its name. The concept had existed since 1945. The 4467 invented it, the 5028 omitted it, and 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~~.

The 6105 is the first Rolex reference to print ''Datejust'' on the dial. Earlier Datejusts already existed as catalog references, but the dials still said "Oyster Perpetual." In case terms the 6105 is still an Ovettone: 36mm, domed back, reeded bezel, gradual date change. What changes here is the name.

== What the 6105 is ==

The 6105 is a ~~successor reference~~. ~~Everything architectural about it —~~ the 36mm Ovettone case, the reeded coin-edge bezel, the domed screw-down ~~caseback~~, the Jubilee ~~bracelet~~ option, the date window at 3 o’clock without a magnifier ~~— carries forward unchanged from the 6074 and 6075 that preceded it~~. The movement ~~evolves one increment,~~ from A.295 to A.296, but both are Aegler automatics ~~from~~ the same ~~family, sized by their diameter to the nearest tenth of a millimeter, and both drive the same slow-creep~~ date ~~mechanism~~. The ~~6105~~ is ~~a continuation rather than a redesign~~.

The 6105 is a continuation of the 6074 and 6075, not a redesign. It keeps the 36mm Ovettone case, the reeded coin-edge bezel, the domed screw-down back, the Jubilee option, and the date window at 3 o’clock without a magnifier. The movement steps from A.295 to A.296, but both are closely related Aegler automatics with the same gradual date change. The dial is where the real change lands: Rolex finally writes ''Datejust'' on the watch.

What the 6105 really resolves is a naming problem. Earlier watches were Datejusts by catalog logic. The 6105 is the point where Rolex finally writes the name on the watch itself.
