Rolex Oyster Perpetual 3348

The Rolex Oyster Perpetual reference 3348 is a rare “Bubbleback” model from the World War II era, with known examples dated to circa 1943. This reference is historically significant as it represents Rolex’s continued production of robust, self-winding chronometers during a period of global conflict. The “Bubbleback” design, with its characteristic domed case back to house the automatic rotor, is an iconic and highly collectible feature of this era. The reference 3348 was typically cased in stainless steel. A particularly notable and sought-after variation of this model features a “California dial,” which has a unique combination of Roman numerals on the top half and Arabic numerals on the bottom half. This distinctive dial configuration, paired with the classic “Mercedes” or “pencil” style hands, makes the reference 3348 a standout among vintage Rolex watches. Its combination of a wartime production date, durable steel construction, and the potential for a rare and desirable dial makes it a significant piece for collectors.
