The world of Rolex collecting is rife with intrigue, filled with rare variations, subtle differences, and occasionally, complete mysteries. While the reference numbers are generally consistent and well-documented, certain gaps and inconsistencies exist, leading to speculation and passionate debate among enthusiasts. This article delves into one such enigma: the purported Rolex 15120. While no officially recognized Rolex reference number exists as 15120, the confusion stems from the historical context surrounding the Calibre 1520 and its predecessor, the Calibre 1530, within the Oyster Perpetual Date line. This exploration will clarify the situation and address related searches like "Rolex 15200 price," "Rolex 15200 for sale," and other relevant model specifications.
The confusion surrounding a potential "15120" likely originates from the somewhat unusual transition Rolex undertook in the mid-1960s concerning its movements. In 1963, Rolex made a surprising decision: they began phasing out the Calibre 1530, a movement known for its relatively advanced features for its time. Instead of replacing it with a more advanced successor, they opted for the Calibre 1520, a seemingly less sophisticated movement. This retrograde step, atypical of Rolex's usual trajectory of continuous improvement, has puzzled collectors and horologists for decades.
The Calibre 1530, with its higher beat rate and potentially enhanced accuracy, was superseded by the Calibre 1520, which operated at a lower frequency. This change wasn't accompanied by a significant alteration in the external design of the Oyster Perpetual Date watches. Therefore, visually identifying a watch powered by a 1530 versus a 1520 would require opening the case and examining the movement itself. This lack of readily apparent distinction likely contributes to the confusion around potential misidentification or the erroneous creation of a phantom reference number like 15120.
It's highly probable that any reference to a "Rolex 15120" is either a misidentification, a typographical error, or a completely fabricated reference. The existing documentation and established Rolex reference guides do not acknowledge a 15120. The confusion is likely linked to the relatively similar Calibre 1520, which was indeed used in several Oyster Perpetual Date models. Therefore, understanding the Rolex 15200, its variations, and its market value becomes crucial in disentangling this mystery.
Understanding the Rolex 15200 and Related Models:
The Rolex 15200 is a legitimate reference number, referring to various Oyster Perpetual Date models powered by the Calibre 1520. These watches represent a significant segment of Rolex's production during the 1960s and early 1970s. Their unassuming design, classic elegance, and relatively affordable price (compared to other Rolex models) have made them increasingly popular among collectors and enthusiasts seeking a robust and historically significant timepiece.
