The 1968 Rolex Oyster Perpetual Date ref. 6516 is a vintage timepiece known for its classic design and reliability. It features the signature Oyster case, which is waterproof and robust, embodying Rolex’s famous durability. The “Perpetual” movement refers to its automatic winding mechanism, which recharges itself with the motion of the wrist, eliminating the need for manual winding. The Date complication is displayed at the 3 o’clock position, with a small cyclops lens over it for easier reading. The reference 6516 is often classified as a ladies’ model, and the case size reflects this, measuring 26 mm in diameter. Its smaller case size and elegant design make it a refined choice, especially appealing to those who appreciate vintage Rolex watches.
