Rolex 2230 Description
The time-only version of the Caliber 2235, this automatic movement powered Rolex’s smaller, no-date Oyster Perpetual models from around 1999. As a COSC-certified chronometer, the 2230 offered the same high-beat performance and reliability as its date-displaying sibling, but with the clean, symmetrical dial preferred by many. It was a testament to Rolex’s dedication to providing top-tier chronometric performance in all its watches, regardless of size or complication.
