Water-Resistant to 12,800 ft with the Ringlock system

Rolex has a long tradition of producing superb diving watches. Among them, the Sea-Dweller Deepsea is the Genevan manufacturer's most impressive model. Released in 2008, this 44-mm stainless steel watch is water-resistant to an impressive 3,900 m (390 bar, 12,800 ft). This far exceeds the capabilities of the standard Rolex Sea-Dweller, which has a depth rating of 1,220 m (122 bar, 4,000 ft).

The depth rating is made possible thanks to a special case construction Rolex calls the Ringlock system. Rolex tests each watch in a pressurized container developed by French company COMEX (Compagnie Maritime d’Expertises) to guarantee that every Deepsea can cope with the extreme conditions experienced deep beneath the waves.

An automatic helium escape valve on the left side of the case is a necessary feature for saturation diving and underscores the Deepsea's professional nature. What's more, each movement comes with chronometer certification from the Official Swiss Chronometer Testing Institute (COSC). These movements are especially precise and deviate from the reference time by no more than +/-2 seconds per day. The collection's top model is the D-Blue edition, which features a blue-to-black gradient dial and is highly popular among collectors.

All four Deepsea references have significantly increased in value in recent years. The Deepsea D-Blue ref. 116660 has performed particularly well, appreciating more than 40% between June 2020 and June 2022. Overall, the Deepsea line has proven its appeal to enthusiasts who value a good investment as much as a Rolex watch.

The Design and Technology of the Deepsea

The Sea-Dweller Deepsea can survive at depths to 3,900 m (390 bar, 12,800 ft). This is possible thanks to what Rolex calls the Ringlock system. The watch features a nitrogen-alloyed stainless steel ring at its center, lending the 44-mm 904L stainless steel case its exceptional stability. Combined with a grade-5 titanium case back and 5.5-mm thick sapphire crystal without a Cyclops lens, this watch can withstand three tons of water pressure.

Rolex offers the Sea-Dweller Deepsea in two basic designs. The standard edition has a black dial and a date display at 3 o'clock. There is a white "Deepsea" inscription directly below the brand inscription and the words "Oyster Perpetual Date" at 12 o'clock. The water resistance "12800ft = 3900m," the model name "Sea-Dweller," and its chronometer inscription all sit above 6 o'clock. Finally, the dial's stainless steel edge includes the engravings "Original Gas Escape Valve" and "Ring Lock System."

The Deepsea has a screw-down crown, helium escape valve, and black unidirectional Cerachrom bezel with platinum-coated 60-minute markers. It also comes with a typical Rolex stainless steel Oyster bracelet, which is easy to adjust thanks to its Oysterlock fold-over clasp and practical Glidelock and Fliplock extension systems. Glidelock makes it possible to lengthen the bracelet up to 20 mm in 2-mm increments. Fliplock, on the other hand, allows the bracelet to be lengthened by 26 mm all at once.

The second option is the Deepsea D-Blue. This model differs from the standard model primarily in its dial – even the reference numbers are the same. As indicated by its name, Rolex chose a dial with a gradient that goes from dark blue to black. The only other difference is the relocation of the "Deepsea" inscription to above 6 o'clock, where it shines in bright green. Since Rolex developed this watch in honor of Hollywood legend and "Titanic" director James Cameron's dive into the Mariana Trench, Rolex fans have given it the nickname "Cameron."

The Deepsea's In-House Calibers

Rolex released the second generation of Sea-Dweller Deepsea watches in 2018. These models bear the reference number 126660 and share much of their design with their predecessor, the ref. 116660. The only difference is that the current edition has thinner lugs and case sides.

Perhaps the most significant change took place inside the case. While the ref. 116660 uses the caliber 3135, the ref. 126660 features the caliber 3235. Both movements are certified Superlative Chronometers, tick at 28,800 vibrations per hour (vph), and feature a blue Parachrom hairspring and Paraflex shock protection system. However, the 3235 far exceeds its predecessor in terms of power reserve. Thanks to its Chronergy escapement and longer mainspring, this movement can continue to run for 70 hours when fully wound.

The History of the Rolex Deepsea

The history of the Rolex Deepsea began back in 1960, when marine researchers Jacques Piccard and Don Walsh dove roughly 11,000 m (36,089 ft) into the Mariana Trench in their bathyscaphe, the "Trieste." Rolex had developed the experimental Deep Sea Special specifically for this occasion. The watch was attached to the outside of the submersible and survived the dive completely unscathed. Many of the findings from this experiment later aided in the development of the Rolex Submariner and Sea-Dweller diving watches, which ultimately led to the Rolex Deepsea.

On March 26, 2012, Rolex sent yet another watch into the depths of the Mariana Trench. This time it was on the arm of the Deepsea Challenger submarine piloted by Hollywood director James Cameron. The watch, known as the Deepsea Challenge, was enormous at 51.4 mm in diameter and 28.5 mm thick. The sapphire crystal alone accounted for 14.3 mm. The Deepsea Challenge followed in the footsteps of its ancestor from 52 years prior and withstood the trip to the deepest point on Earth without any problems. Unfortunately, this watch is not for sale.
