Rolex Oyster Royal 6427

The Rolex Oyster Royal ref. 6427 is a manually-wound, time-only model produced primarily during the 1950s and 1960s. Built with Rolex’s classic 34mm stainless steel Oyster case, the watch includes a smooth bezel, acrylic crystal, and the signature screw-down crown and caseback—hallmarks of Rolex’s dedication to water resistance. It is powered by the Rolex Caliber 1210, a manual-wind movement known for reliability and simplicity. The dials were typically restrained in design, offered in silver, white, or champagne tones with applied baton or numeral hour markers and pencil hands. The lug-to-lug length measures around 41mm, with a lug width of 19mm, maintaining balanced proportions ideal for smaller or traditionally sized wrists. As part of the ‘Royal’ sub-line, this reference reflected modest elegance and was considered a refined yet accessible option within the Rolex catalog. Today, the 6427 appeals to collectors for its classic design, reliability, and understated vintage appeal.
