Rolex Oyster Perpetual 6050

The Rolex Oyster Perpetual ref. 6050, commonly known as the ‘Bubbleback,’ is a distinguished vintage model from the late 1940s to early 1950s. It features a compact 32mm case crafted in stainless steel or gold, characterized by its prominent rounded caseback, domed acrylic crystal, and screw-down crown that provides reliable water resistance. This reference is powered by the Rolex Caliber 620, a bi-directional automatic movement famed for its robust construction and reliability, offering approximately 42 hours of power reserve. Dial variations typically included silver or champagne finishes with applied baton markers, Arabic numerals, dauphine or leaf-style hands, and radium lume for nighttime visibility. Its lug-to-lug measurement is about 39mm, and the lug width is 17mm, making it particularly suitable for smaller wrists or those seeking a historically accurate wrist presence. The ref. 6050 represents a significant transitional period for Rolex, marking the move from earlier Bubbleback models toward modern Oyster Perpetual designs. Collectors prize this reference for its historical significance, iconic design, and important role in Rolex’s development of automatic waterproof wristwatches.
