A neat slice of Rolex history from the early 1960s, this Air‑King Date Ref. 5700 mixes the brand’s pilot‑watch roots with a practical date window at 3 o’clock, something its sibling the ref. 5500 didn’t have. Originally introduced in the late 1950s, the 5700 was Rolex’s answer for those who wanted everyday usability wrapped in classic Oyster steel. With a 34 mm stainless steel case and a clean silver dial, this vintage Air‑King has a timeless, tool‑watch vibe that still feels elegant today. Inside ticks Rolex’s automatic movement, the Calibre 1570. As a model produced in smaller numbers than the standard Air‑King, the 5700 is a subtle but rewarding pick for anyone who loves low‑key vintage Rolex with a bit of everyday practicality.
