Rolex Oyster Speedking 6021

The Rolex Oyster Speedking ref. 6021 is an early post-war manually-wound wristwatch, reflecting the compact and durable design principles that defined the Speedking line. Produced in the 1940s and early 1950s, the watch features a 30.5mm stainless steel Oyster case with a smooth bezel, acrylic crystal, and Rolex’s patented screw-down crown and caseback for water resistance. It is powered by the Rolex Caliber 710, a dependable manual-wind movement with basic time-only functionality. Dials on the 6021 were typically restrained in design, available in silver or white with applied or printed numerals, and paired with pencil or leaf-style hands for easy legibility. The lug-to-lug measurement is approximately 36mm, and the lug width is 17mm, giving the watch a refined and balanced wrist presence. As one of the earlier Speedking references, the 6021 is notable for embodying Rolex’s evolution from tool-watch utility to stylish minimalism, and it holds particular value for collectors of wartime and post-war Rolex production.
