Rolex watch collecting is a richly entertaining excursion into horological craftsmanship, history, and exclusivity. While most Rolex watch garner interest among enthusiasts around the globe, few are the “holy grail” that buyers wait their whole careers to acquire. The rarest Rolex watches often have specific dial variations, very limited production, and consequential historical significance. These replica watches UK are more than luxury accessories; they’re pieces that house specific moments within the history of Rolex watchmaking.
The 5 Most Rare Rolex Watches You Should Know
The following list represents the pinnacle of Rolex rarity, featuring vintage Rolex watches that are just as much prized for their historical significance as they are for their rarity. As you will come to find out, each watch tells its own story about the brand’s evolution.
1. Rolex Daytona Ref. 6240 with Retailer-Signed Dial
The Rolex Daytona ref. 6240 is significant because it was the first model to feature screw-down pushers, which allowed Rolex to finally designate its resident chronograph with the distinction, “Oyster.” Made during the mid-1960s, the watch was a notable technical improvement. However, perfect copy Rolex watches that come up with retailer-signed dials, like those issued by the famed Tiffany & Co., push this watch to a whole other level of collectability.
Double-signed dials signify that the watch was once retailed by high-end jewelers, something Rolex stopped allowing during the 1990s as the brand shifted to more centralized distribution. Tiffany & Co. signed Rolex dials are amply documented and sell for high amounts at auctions. Provenance is paramount for any double-signed dial. For example, collectors will look for confirmation that the dial is original and that the stamping is period-correct.
2. Rolex Submariner ref. 5510 “Big Crown”
Rolex Submariner 5510 received the “Big Crown” name due to the hulk-sized 8mm winding crown, much bigger than the standard crowns utilized on other Submariner models. Made only for a short time around the year 1958, specialists suppose that as little as 300 pieces were produced, making it one of the rarest production Submariners. While the ref. 5510 shares the same oversized crown profile as the famous ref. 6538, the watch featured in the early James Bond movies was, in fact, the ref. 6538, not the ref. 5510.
The ref. 5510’s short distribution period and striking style details have made it one of the most sought-after used Submariners among those on the hunt for the rare and exclusive best fake Rolex watches.
3. Rolex Milgauss ref. 6541 with Smooth Bezel
Rolex created the Milgauss exclusively for scientists and engineers who worked under high-magnetic-environment conditions, as high magnetic forces can interfere with the accuracy of a mechanical watch. “Milgauss” is the term used to describe the resistance to 1,000 gauss of magnetic force, a feat obtained through the use of a Faraday cage (soft iron inner case) that protects the movement. The Rolex 6541, introduced in the late 1950s, was one of the first Milguass models.. Inside most examples of that model is the caliber 1066.
Though the ref. 6541 is collectible to begin with, examples with a smooth bezel are much rarer. A vast majority of the Milgauss 6541s left the factory with a rotating bezel, so the smooth bezel version is a rare configuration. Smooth bezel 6541s are thought to have been made in very limited numbers for the U.S. market, which makes them especially sought after by collectors in the know.
4. Rolex Daytona ref. 6263 with Tropical Sub-Dials
Rolex Daytona ref. 6263 is among the rarest “Paul Newman” Daytona references, made during the 1970s and 1980s. While any “Paul Newman” Daytona would be interesting to a collector, pieces showing “tropical” dials hold even more value. When “tropical” dials occur, it is the result of natural aging and long-term ultraviolet radiation, which changes the original black finish to brown or chocolate colors.
This color shift cannot be reproduced or forecasted, so each Rolex 6263 tropical dial is one-of-a-kind. Tropical dials command high prices in the market as their natural patina and personal character are highly valued by vintage high quality fake Rolex watches enthusiasts. The level of color shift ranges, watch to watch, and condition, as well as evenness of color, significantly influence value.
5. Rolex Sea-Dweller ref. 1665 “Double Red, Patent Pending”
Rolex designed the Sea-Dweller for working saturation divers who required a watch that would withstand extraordinary depths, as well as the specific problem of helium being present in the case during decompression. The original Rolex 1665, released for regular production in 1967, had a then-revolutionary helium escape valve that would purge trapped helium from the case without injuring the crystal or case integrity.
The first production pieces, produced between 1967 and 1977, were nicknamed “Double Red” due to the double lines of red lettering on the face indicating “Sea-Dweller” and “Submariner 2000.” Early examples also included “Patent Pending” wording on the case back, referring to the patent pending on the helium escape valve before the patent itself was issued. These “Patent Pending” pieces are the earliest production Sea-Dwellers and are incredibly rare compared to the later “Double Red” pieces without this case back inscription.
