Rolex Worth Rmb 4.88 Million, Best Fake Rolex

In 2018, Phillips auction house auctioned a rare Rolex Sea-Dweller prototype watch Ref. 1665. The final transaction price was as high as 708,500 Swiss francs, approximately RMB 4.88 million.

To adapt to deep-sea saturation diving, Rolex modified the Submariner series Ref.5513, added a new patented “helium escape valve” on the side of the case, and then dedicated a single row of Ref.5514 for Comex use. Best fake Rolex.

The “helium escape valve” has also become the distinguishing point between the Sea-Dweller and Submariner series.

Many people think that the helium escape valve is very high-tech. It can automatically adjust the pressure inside and outside the watch case to prevent the mirror from breaking. The structure of the helium escape valve is straightforward: just a waterproof rubber ring, a short metal rod, and a spring leaf. The working principle is the same as the pressure cooker valve used at home.

When the pressure inside the watch case is high, the spring leaf deforms and bulges the metal rod outward. The high-pressure gas inside takes the opportunity to be released through the gap between the metal rod and the watch case. Once the internal and external pressures are balanced and the spring leaf returns to its original shape, it will naturally drive the metal rod to retract and isolate external moisture through the rubber ring.

After further upgrades, the waterproof depth was increased from 200 meters to 500 meters, and the dial began to be marked with a line of red fonts “Sea-Dweller” and white fonts drawn “Submariner Water Ghost,” which is commonly known as “Sea-Dweller.” “Single Red”. Up to this period, it was still a small-scale experimental stage, and the “Sea-Dweller” was still affiliated with the “Submariner.”

Ten years later, in 1977, Ref. 1665, officially released to the public, canceled the design of the two lines of “Sea-Dweller” and “Submariner” printed in red fonts on the dial and only used white uppercase markings. “Sea-Dweller”. 1977 was also the critical year when the Sea-Dweller series broke away from the Submariner series in a narrow sense and became its school.

The Rolex Ref.1665 prototype watch sold this time belongs to American diver Robert Palmer Bradley. At that time, his job was to pilot the deep-sea submersible “Deepstar-4000” designed by the famous ocean explorer Jacques Cousteau, on the east coast of the United States and the Caribbean. The area conducts diving, studies marine geology and biology, and is affiliated with the U.S. Naval Office of Oceanography.

In November 1968, Rolex presented this watch to Robert Palmer Bradley to commemorate the 500th dive of Deepstar-4000. Most of the original engraved writing on the back of the case has been lost, but Bob’s name and the month 11 can be vaguely distinguished.

However, not all Sea-Dweller prototype watches were equipped with a “helium escape valve” because they were still being developed and tested. Not many have survived the years since these watches were prototypes and only a few intense field tests. Researchers have found 12 “Single Red” Sea-Dwellers, seven of which do not have helium escape valves. Luxury replica watches.

At the same time, according to statistics from Jose Perez, Robert’s current Rolex, numbered “1602913,” is the earliest known Sea-Dweller Ref. 1665.
