The Submariner is one of Rolex's most iconic models. Still in production today, it has gone through multiple incarnations throughout its 65 year history. While early generation examples notably had either a "small" or "big" crown, Rolex gradually introduced crown guards to make the model more robust and durable.

The history of the "no crown guards" Submariner is marked by several milestones. Launched in 1953, the very first serially produced Submariner wristwatch carried the designated reference 6204. Displaying pencil hands and luminous numerals, it was an incredibly important aid for dives. Rolex eventually developed other "small crown" models, such as reference 6205, 6536/6538, 6536 and 6536/1, while reference 6538 and 5510 were fitted with a "large" crown. Reference 5508 was the last Submariner to carry the "100m=330ft" depth rating.

The Submariner model is further immortalized on film, having accompanied James Bond on multiple secret missions in Dr. No, From Russia With Love, Goldfinger, and Thunderball. Bond’s gadget is disguised as a wristwatch, which is equipped with different spying abilities.

This reference 5508 is a superlative example. Offered in unpolished condition, it is truly a marvel to behold. The contrasting polished and brushed finishes are undoubtedly original, and display how reference 5508s originally left the factory. Furthermore, there is a crisp Portuguese import mark stamped on the upper left lug. It would have disappeared if the watch had been repolished in any way. Additionally, the dial is in excellent and incredibly glossy condition with an incredible mirror-like finish. It barely displays any sign of aging. The "exclamation" mark corresponds with the serial number. Even the bracelet is incredibly rigid and crisp, leading us to believe the watch was worn very rarely throughout its lifetime. The inside case back and movement are in pristine condition; it is possible that this is the first time the watch has been opened in fifty six years.
