ROLEX Perpetual Date 1530 Made in 1975 Oyster 50th — USD 20,700

The Rolex Reference 1530 is notable for its distinctive case design, which predates and shares characteristics with the Oysterquartz models, yet houses a mechanical movement. This reference represents a transitional period in Rolex design, offering a unique aesthetic that sets it apart from the more traditional Oyster Perpetual cases of its era. It was produced in limited quantities, contributing to its specialized appeal among collectors. The integration of a mechanical caliber within this angular case profile provides a different wearing experience compared to its more common contemporaries. This reference features a stainless steel case measuring 36 mm in diameter, a departure from the typical round cases. It is fitted with an acrylic crystal and a smooth bezel. The watch is powered by the automatic Rolex Caliber 1570, a robust and reliable movement known for its precision. This movement provides a power reserve of 48 hours and includes a date complication, visible through an aperture on the dial. The water resistance is rated at 100 meters, consistent with Rolex's Oyster case standards. For collectors, the Reference 1530 is significant due to its unusual case architecture and its mechanical heart, making it a precursor to the Oysterquartz line. It appeals to those interested in the evolution of Rolex design and production anomalies. Its scarcity and unique design language differentiate it from other Oyster Perpetual models, positioning it as a distinct piece within the brand's history. The silver dial and Oyster bracelet complete its integrated design.
