Rolex Oyster Perpetual 2490

The Rolex Oyster Perpetual reference 2490 is a vintage “Bubbleback” model produced in the immediate post-World War II era. Its historical context places it among the early examples of Rolex’s pioneering self-winding, waterproof wristwatches. The “Oyster” case and “Perpetual” movement were significant innovations that established Rolex’s reputation for robust and reliable timepieces. The reference 2490 is notable for its tonneau-shaped case, a design characteristic of the period, and its screw-down “Oyster” crown and case back, which ensured its water resistance. A significant variation of this reference is the “Army Dial,” featuring a black dial with a combination of luminous Arabic and Roman numerals or baton hour markers for enhanced legibility, a feature purportedly favored by military personnel of the time. The hands were also luminous. These dials contribute to the watch’s desirability among collectors. The case is made of stainless steel. Due to its historical significance as an early and distinct example of the Oyster Perpetual line, the reference 2490 is a sought-after collector’s piece.
