Rolex Datejust 6105

Reference 6105 is an iconic and foundational 36mm Oyster Perpetual Datejust, produced from approximately 1951 to 1954. It is a prime example of the early ‘Ovettone’ or ‘Big Bubbleback’ design. It is powered by the Rolex Caliber A.296, a non-quickset automatic movement, often with a ‘roulette’ date wheel. The technical specification 6105 denotes a model with a finely milled or ‘fluted’ bezel, typically in 18k gold. The Ref. 6105 is historically significant as it was one of the first models to feature the ‘Cyclops’ magnifier lens, introduced around 1953. It established the definitive aesthetic of the Datejust: the 36mm case, fluted bezel, and magnified date.
