The present Rolex Oyster Perpetual reference 2764 is a superb and extremely rare example of the legendary “Bubbleback” — arguably one of the most important model in Rolex’s early evolution as a manufacturer of waterproof automatic wristwatches. Produced between the early 1930s and mid-1950s, these watches earned their enduring nickname from the rounded caseback, designed to accommodate the rotor mechanism of Rolex’s pioneering self-winding movement. What makes this particular example especially enticing is the seldom-seen “Erbe-Basel” retailer signature, a subtle yet significant mark of provenance that points to the long-standing collaboration between Rolex and the Erbe boutique in Basel during the golden era of the brand. Even more notably, the watch is fitted with a sought-after Gay Frères stainless steel bracelet. Measuring 31mm in diameter, the case offers compact proportions by today’s standards, yet wears with a surprising presence thanks to its sculpted lugs and robust Oyster architecture. A charming relic of Rolex’s formative years and a true collector’s gem, this Bubble Back stands out not just for its preserved condition, but also for its rare dial signature and undeniable historical appeal.
