About the Deepsea
The Deepsea is the biggest, heaviest, deepest-rated dive watch Rolex has ever produced. Rated to 3,900 meters on the genuine — deeper than 99% of divers will ever go. We list 4 references. Iconic James Cameron D-Blue 116660 made to commemorate the 2012 solo Mariana Trench dive, the 136668LB that Rolex added in 2024, standard black 116660, 40mm Sea-Dweller 126660 for smaller wrists. Want the Swiss ETA-clone caliber? That version is $999; with a Japanese Miyota automatic the same Deepsea starts at $359.
The Deepest Watch Rolex Has Ever Built
Story of the Deepsea starts in 1967 with a different watch called the Sea-Dweller. Rolex built it for a specific kind of professional diver — saturation divers who live for days or weeks at a time in pressurized chambers at the bottom of the North Sea, working on oil rigs or undersea pipelines. Not recreational divers. Industrial workers in the most extreme environment on earth. Needed a watch that could survive depths far beyond what the Submariner was rated for. Sea-Dweller solved that, and added one feature the Submariner doesn't have. A tiny one-way valve in the side of the case that lets helium gas escape during decompression. Saturation divers breathe a helium-oxygen mixture. Helium molecules are small enough to seep through the case seals during long pressurized stays. Without an escape valve, the helium would build up inside the watch and pop the crystal off when the diver returned to surface pressure. Sea-Dweller's helium escape valve solved that problem in 1967 and is still used today.
Deepsea was launched in 2008 as the bigger, more extreme version of the Sea-Dweller. Watch that pushed Rolex's depth rating to 3,900 meters — about 12,800 feet — deeper than the average depth of the Mariana Trench. Way Rolex did this is the engineering story most people miss. Instead of just making the case thicker, Rolex invented a system called Ringlock. Crystal is 5.5mm thick (versus the Submariner's 1.5mm). Around the inside of the case is a nitrogen-alloyed steel compression ring that distributes the inward pressure of seawater across the crystal and the caseback together, instead of letting all the force concentrate on the crystal alone. Case can withstand pressure that would crush a normal dive watch like a soda can, and does it without being absurdly thick. Deepsea is still 17.7mm thick (about 4.7mm thicker than a Submariner) and weighs around 220 grams on the bracelet, roughly 70 percent heavier than a Submariner. You feel the Deepsea on your wrist the moment you put it on. That weight is part of the watch.
The most famous Deepsea is the D-Blue 116660. March 2012, filmmaker James Cameron — director of Titanic and Avatar — made a solo descent in a custom submersible called the Deepsea Challenger to the Challenger Deep, the deepest known point in the Pacific Ocean at 10,908 meters. First person in 52 years to reach the bottom of the Mariana Trench. Strapped to the outside of his submersible's robotic arm was a Rolex experimental prototype called the Deepsea Challenge, rated to 12,000 meters. The watch survived the dive. To commemorate it Rolex released a special version of the production Deepsea (still reference 116660) with a unique dial that fades from a bright surface blue at the top to total ocean black at the bottom. Gradient represents the literal journey from sunlit shallow water down into the absolute darkness of the deep sea. Collectors immediately nicknamed it the D-Blue or the James Cameron. Most photographed Deepsea variant ever made and the cornerstone of the Deepsea family today.
What we copy and what we don't. 44mm case dimensions, 17.7mm thickness, lug-to-lug span, wrist-crushing weight, Cerachrom-style ceramic bezel, helium escape valve at 9 o'clock (it's there and looks correct, though our valve is decorative — your watch is not going saturation diving), D-Blue gradient with the correct fade from bright blue to total black, Ringlock case profile, Oyster bracelet with the Glidelock and Fliplock extension links. All of that we get right. On the genuine, the 136668LB is solid 18k yellow gold with an RLX titanium caseback; ours is gold-plated, makes no titanium claim, and its product page lists the case finish. Where we cannot match the genuine: the 3,900-meter pressure rating. Ours is splash-safe, about 30 m, regardless of what the dial claims. Ringlock system is built around precisely-tolerance components, certified pressure testing, and specific gasket materials that are not economical at these prices. If you are actually planning to dive, buy a genuine Deepsea or use a dive computer. For everyone else — essentially everyone — the look and wrist presence are there.

What to Expect
44mm of Ringlock Presence
Full 44mm Ringlock presence from $359 with a Japanese Miyota automatic (about 40 hours of reserve), or from $999 with a Swiss ETA-clone caliber (about 70 hours).
Real Ringlock Case Profile
44mm case, 17.7mm thick, shaped to the Ringlock profile of the genuine Deepsea, whose compression ring sits inside its case. Same case shape, same crystal thickness silhouette, same wrist presence as the real 116660.
James Cameron D-Blue Dial
Iconic 116660 D-Blue dial commemorating James Cameron's 2012 solo descent to the Challenger Deep. Gradient fades from bright surface blue at the top to total ocean black at the bottom. Most photographed Deepsea variant ever made.
136668LB, the 2024 Gold Deepsea
Rolex added the 136668LB in 2024: the Deepsea in solid 18k yellow gold with a blue dial, an RLX titanium caseback and about 320 grams on the wrist. Ours reproduces the look with gold plating, not solid gold, and makes no titanium claim.
Helium Escape Valve at 9 O'Clock
Signature one-way helium release valve from the Sea-Dweller heritage. Visually present and correctly placed at 9 o'clock on every reference, though ours is decorative. Your watch is not going saturation diving.
Heaviest Sport Rolex on the Wrist
44mm Deepsea weighs around 220 grams on the bracelet — roughly 70 percent heavier than a Submariner. You feel it the moment you put it on. That weight is part of the watch.
Deepsea Super Clone: Frequently Asked Questions
What is the difference between the Sea-Dweller and the Deepsea?
Both are Rolex professional dive watches, distinct references with distinct purposes. Sea-Dweller (current reference 126600, our catalog 126660, 40mm) is the more wearable dive watch. Rated to 1,220 meters, with the helium escape valve, suitable for daily wear and for actual saturation diving. Deepsea (genuine references include the 136660 in steel, from 2022, and the 136668LB in yellow gold, from 2024, both 44mm) is the larger and more extreme variant. Rated to 3,900 meters using the patented Ringlock case architecture with the 5.5mm-thick sapphire crystal and the internal compression ring. Sea-Dweller is for divers who actually dive every day. Deepsea is for the deepest-rated production dive watch in the world plus the wrist presence and weight to match. Same Sea-Dweller family DNA. Deepsea is bigger, thicker, heavier, rated three times deeper.
What is the James Cameron D-Blue Deepsea?
D-Blue is the collector nickname for the Deepsea reference 116660 with the gradient blue-to-black dial. Released by Rolex in 2014 to commemorate filmmaker James Cameron's 2012 solo descent to the Challenger Deep at 10,908 meters — the deepest known point in the Pacific Ocean. Cameron was the first person in 52 years to reach the bottom of the Mariana Trench, and Rolex strapped an experimental prototype Deepsea Challenge (rated to 12,000 meters) to the outside of his submersible's robotic arm during the dive. The watch survived. To honor it, Rolex released the production 116660 with a dial that fades from bright surface blue at the top to total ocean black at the bottom. Literal visual journey from daylight down into total deep-sea darkness. Most photographed Deepsea variant ever made.
What is the Deepsea 136668LB?
136668LB is the gold Deepsea, introduced by Rolex in 2024. Same 44mm case and 3,900-meter rating as the steel model, but the case and bracelet are solid 18k yellow gold, the dial is blue, and the caseback and helium escape valve are RLX titanium. All that gold makes it heavy: about 320 grams. The steel Deepsea is a separate reference, the 136660, introduced in 2022 with an RLX titanium caseback of its own. Ours reproduces the look of the 136668LB with gold plating over the case; the solid gold and the titanium caseback stay genuine-only.
Is ours waterproof to 3,900 meters like the genuine Deepsea?
No. Watches at this price are typically pressure-tested to roughly 30 meters of water resistance at most, regardless of what the dial claims about 3,900 meters. Ringlock case architecture in the genuine Deepsea relies on precisely-tolerance components, certified pressure testing, specific gasket materials, and quality control standards that are not economical at this price. Ours handles hand washing, rain, a pool splash. Call it 30 meters of real-world water resistance. Not a dive watch. If you are actually planning to dive, buy a genuine Deepsea or use a dedicated dive computer. Your life depends on it. For everyone else the look and wrist presence of the Deepsea are completely there.
Which Deepsea should I actually buy?
Buy the James Cameron D-Blue 116660. Blue-to-black gradient dial is the most beautiful modern Rolex dial in the catalog and the watch tells a story nobody else's wrist can tell — the actual story of the deepest manned ocean descent in human history. Iconic Deepsea, the one every collector says to own first. For the gold-and-blue look, the 136668LB comes second; the solid 18k gold and the RLX titanium caseback belong to the genuine, and ours is gold-plated. Standard black-dial 116660 is the third pick. Great watch, but the D-Blue is the same watch with the more interesting dial. Skip the 40mm Sea-Dweller 126660 unless your wrist is under about 7.5 inches, where our fit table starts the 44mm, and the 44mm Deepsea actually feels too big. Start with the D-Blue.
Why is the Deepsea so much bigger and heavier than the Submariner?
Pressure rating math. Submariner is rated to 300 meters of water with a 13mm-thick case and a 1.5mm sapphire crystal. Deepsea is rated to 3,900 meters — 13 times deeper — and the physics of holding back that much water pressure require a much thicker case, a much thicker crystal, and structural reinforcement. Deepsea uses a 5.5mm-thick sapphire crystal (more than three times the Submariner's), a 17.7mm-thick case (4.7mm thicker than the Submariner), and the patented Ringlock system. Nitrogen-alloyed steel compression ring around the inside of the case that distributes the inward pressure of seawater across the crystal and the caseback together. Result is a watch that weighs about 220 grams on the bracelet versus around 150 grams for a Submariner — roughly 70 percent heavier. Deepsea is not bigger because Rolex thought it looked cool. Every extra millimeter and every extra gram is structural pressure containment.
