The Rolex Oyster Perpetual Date Ref. 15000 is one of the classic 34mm bridge models that the brand launched around 1980 and produced until the late 1980s. It replaced the previous generation Ref. 1500 model, bringing significant modernization to the movement and technical infrastructure. Movement: Rolex Calibre 3035 The most critical point that distinguishes the Ref. 15000 model from its predecessors is the Calibre 3035 movement housed within it: Quickset (Quick Date Setting): By pulling the crown to the second position, it allows the date hands to advance independently without rotating them for 24 hours. High-Beat: The movement speed has been increased from 19,800 vph to the modern standard of 28,800 vph (4 Hz); this results in a smoother seconds flow and higher accuracy. Power Reserve: Approximately 48 hours. Certification: Independently COSC certified (Superlative Chronometer Officially Certified).
