ROLEX SUBMARINER REF. 5508 IN STAINLESS STEEL - From 1958 Reference N° 5508 Serial N° 400323 Year: 1958 Material: Stainless steel Dimensions: 37mm Caliber: Automatic cal. 1530 Crystal: Plexy Strap: Nato Early versions of the Submariner reference 5508 were distinguished by their 'small' or 'large' crowns, which have now become highly collectible. Over time, Rolex introduced crown guards to improve the watch's durability and robustness, cementing the Submariner's reputation as a professional-grade diving watch. The Submariner 'Small Crown' ref. 5508, produced between 1958 and 1962 before being replaced by the reference 5513, represents a transitional chapter in Rolex's legendary history. This reference is among the last to feature the '100 m = 330 ft' depth rating combined with a crown-protected design. Its glossy black dial has aged elegantly, displaying a charming patina on the hour markers. This diving watch has become a true icon, revered among collectors. In good overall condition, the watch is currently working.
