I know you really want to know about the Rolex Deepsea 116660 vs 126660 which is better, the key takeaway is this: both are built for extreme depths and share the same 3,900-meter water resistance, but the 126660 is a clear upgrade in movement, comfort, and long-term value. The biggest change is the Caliber 3235 movement in the 126660, which offers a 70-hour power reserve—nearly three days—compared to the 116660’s 48-hour Caliber 3135. This means less winding and better performance over time.
Other improvements in the 126660 include a wider 21mm Oyster bracelet, redesigned lugs for better fit, slightly larger crown guards, and enhanced overall comfort. While both models are no longer in production (replaced by the 136660), they remain popular on the pre-owned market. The 116660 typically sells for $8,000–$15,000, while the 126660 commands $11,500–$17,000, reflecting its newer tech and stronger resale appeal.
Whether you’re drawn to the original rugged look of the 116660 or the modern upgrades of the 126660, understanding these differences helps you make a smart, informed choice.
Overview: What Are the Rolex Deepsea 116660 and 126660?
The Rolex Deepsea is one of the toughest dive watches ever made. Designed for deep-sea exploration, it’s not just a tool—it’s a statement of engineering excellence. When people talk about the Rolex Deepsea 116660 vs 126660, they’re comparing two generations of this legendary timepiece.
The ref. 116660 was introduced in 2008 and produced until 2018. It was the first commercially available Deepsea model and set a new standard with its 3,900-meter depth rating. It used Rolex’s trusted Caliber 3135 movement and featured a bold 44mm case with a titanium case back and Ringlock system.
The ref. 126660 replaced it in 2018 and was made until 2022. It kept the same extreme water resistance but brought meaningful upgrades: a newer movement, improved bracelet, and subtle design tweaks. It was succeeded by the ref. 136660 in 2022.
| Feature | Rolex Deepsea 116660 | Rolex Deepsea 126660 |
|---|---|---|
| Production Years | 2008 – 2018 | 2018 – 2022 |
| Movement | Caliber 3135 | Caliber 3235 |
| Power Reserve | 48 hours | 70 hours |
| Bracelet Width | 20mm | 21mm |
| Case Diameter | 44mm | 44mm |
| Water Resistance | 3,900m (12,800ft) | 3,900m (12,800ft) |
| Case Material | Oystersteel (904L) | Oystersteel (904L) |
| Case Back | Titanium | Titanium |
Both models are built for professionals and collectors who demand reliability under pressure. While they look nearly identical at first glance, the details tell a different story—one of evolution and improvement.
Water Resistance: Same Extreme Depth Rating
The most impressive thing about both the Rolex Deepsea 116660 vs 126660 is their ability to survive at 3,900 meters (12,800 feet). That’s deeper than the wreck of the Titanic and far beyond any recreational dive limit. This rating is made possible by the Ringlock System, a patented Rolex technology that combines a thick 5.5mm sapphire crystal, a compression ring, and a titanium case back to handle extreme pressure.
Even more remarkable? Rolex doesn’t just test these watches to 3,900 meters. They test them to 4,875 meters (16,000 feet)—a 25% safety margin. This is standard for all Rolex dive watches and ensures that every Deepsea can handle real-world conditions with room to spare.
The testing process involves placing the watch in a high-pressure chamber filled with a helium-rich gas mix. It’s then subjected to pressures exceeding its rated depth. Afterward, it’s checked for condensation and function. Only watches that pass are certified.
So when it comes to water resistance, there is no difference between the 116660 and 126660. Both are equally capable of withstanding the ocean’s deepest points.
Movement: The Biggest Upgrade
If you’re trying to decide between the Rolex Deepsea 116660 vs 126660, the movement is where the real difference lies.
The 116660 uses the Caliber 3135, a workhorse movement that powered many Rolex models for over 30 years. It’s reliable, accurate, and well-proven. But it has a 48-hour power reserve, meaning the watch stops after two days off the wrist.
The 126660, on the other hand, uses the Caliber 3235, a next-generation movement introduced in 2015. This is a major leap forward. It offers a 70-hour power reserve, so you can take it off Friday night and put it back on Sunday evening without resetting the time.
But it’s not just about battery life. The Caliber 3235 is more efficient thanks to Rolex’s Chronergy escapement, which improves energy transfer by 15%. It’s also more accurate, rated to -2/+2 seconds per day, and requires less maintenance over time.
| Movement Feature | Caliber 3135 (116660) | Caliber 3235 (126660) |
|---|---|---|
| Power Reserve | 48 hours | 70 hours |
| Escapement | Traditional | Chronergy |
| Accuracy | -2/+2 sec/day | -2/+2 sec/day |
| Efficiency | Standard | Improved |
| Introduced | 1988 | 2015 |
This upgrade makes the 126660 more convenient and future-proof. If you value modern watchmaking tech, the 126660 wins hands down.
Design and Case Changes
At first glance, the Rolex Deepsea 116660 vs 126660 look almost identical. Both have the same 44mm case, thick domed sapphire crystal, and aggressive dive watch styling. But there are subtle yet meaningful design changes in the 126660.
One of the most noticeable updates is the crown guards. The 126660 has slightly larger crown guards, giving it a bolder, more protective look. This not only improves aesthetics but also adds extra security for the winding crown—critical in deep-sea environments.
The lug design has also been updated. The 126660 features redesigned lugs to accommodate a wider bracelet. While the 116660 has a 20mm Oyster bracelet, the 126660 uses a 21mm bracelet. This might sound like a small change, but it improves how the watch sits on the wrist and enhances comfort.
Some sources claim the lug width is 22mm, but multiple trusted reviews and official specs confirm 21mm for the 126660 and 20mm for the 116660. This consistency across high-authority sites like Bob’s Watches and WatchGuys supports the 21mm measurement.
Another minor update is the chapter ring font on the dial. The 126660 features a more modern font that matches the “DEEPSEA” and “SEA-DWELLER” text better, giving it a cleaner, more cohesive look.
So while the overall design language remains the same, the 126660 feels more refined and modern.
Bracelet and Comfort
The bracelet is more than just a strap—it affects how the watch feels on your wrist. And when comparing the Rolex Deepsea 116660 vs 126660, the 126660 has the edge in comfort.
Both models come with the Oyster bracelet and include Rolex’s Glidelock and Fliplock extension systems. Glidelock lets you adjust the bracelet length by up to 20mm in 2mm increments without tools. Fliplock adds a 27mm extension, perfect for wearing over a dive suit.
But the 126660’s 21mm bracelet with redesigned lugs spreads the weight more evenly. This makes a big difference given the watch’s 210-gram weight. The 116660, while solid, can feel a bit top-heavy due to the narrower 20mm lugs.
The 126660 also has slightly better finishing and tighter link tolerances, reducing bracelet wiggle and improving long-term wear.
So while both are built for durability, the 126660 offers a more balanced, comfortable experience—especially during extended wear.
Dial Options: D-Blue and the James Cameron Tribute
One of the most iconic features of the Deepsea is the D-Blue dial. This special gradient dial transitions from deep blue at the top to black at the bottom, symbolizing the ocean’s descent into darkness.
Both the 116660 and 126660 offer the D-Blue dial as an option. It was first introduced in 2012 to honor filmmaker James Cameron’s solo dive to the Mariana Trench in a submersible equipped with a Rolex Deepsea Challenge watch.
The D-Blue model is often called the “James Cameron” Deepsea, though it’s not officially named that by Rolex. It carries a premium of $300–$1,000 over the black dial version, depending on condition and market demand.
| Dial Option | Available on 116660? | Available on 126660? | Premium Over Black Dial |
|---|---|---|---|
| Black | Yes | Yes | — |
| D-Blue | Yes | Yes | $300 – $1,000 |
The D-Blue dial is more than just a color—it’s a tribute to human exploration and Rolex’s role in deep-sea history. For many collectors, it’s the only way to own a Deepsea.
Price: What Do They Cost?
Now let’s talk numbers. The Rolex Deepsea 116660 vs 126660 price difference is significant, especially in the pre-owned market.
When new, the MSRP for a steel Deepsea was $14,250, with the D-Blue dial adding a $310 premium. But neither model is in production anymore, so you’ll be buying pre-owned.
Here’s a breakdown of current secondary market prices:
| Model | Dial | Price Range (USD) | Notes |
|---|---|---|---|
| 116660 | Black | $8,000 – $10,000 | Older movement, lower value |
| 116660 | D-Blue | $12,000 – $15,000 | Collector demand boosts price |
| 126660 | Black | ~$11,500 | Newer tech, better retention |
| 126660 | D-Blue | $14,000 – $17,000 | Strong resale, high demand |
One report notes that the 126660 James Cameron model launched at just over £9,500 in 2018 but quickly rose to £17,900 on the secondary market—showing strong demand and appreciation.
In the U.S., grey market prices show the 126660 D-Blue selling for $13,900 and the black dial for $10,700. Authorized dealers no longer carry these models, so prices are driven by supply and collector interest.
The 126660 holds more value because of its newer movement, improved comfort, and modern design. If you plan to keep or resell, it’s the smarter investment.
Materials and Build Quality
When it comes to materials, both the Rolex Deepsea 116660 vs 126660 are built to the same high standard.
The case is made from Oystersteel, Rolex’s proprietary 904L stainless steel. This alloy is more corrosion-resistant than standard 316L steel and holds a better polish. It’s also harder, making it more scratch-resistant.
The bezel features a Cerachrom insert made of black ceramic. This material is virtually scratch-proof and won’t fade in sunlight—ideal for a dive watch exposed to harsh conditions.
The case back is made of titanium in both models. This lightweight metal reduces overall weight and improves comfort, despite the watch’s rugged build.
Both watches also include a helium escape valve, a must-have for saturation divers. It allows built-up helium gas to escape during decompression without damaging the watch.
So in terms of materials and construction, there’s no difference between the two. Both are built like tanks.
Which One Should You Buy?
So, which model is right for you? Let’s break it down.
Choose the 116660 if:
- You want a lower entry price
- You like the original Deepsea design
- You don’t mind the older 48-hour movement
- You’re on a budget but still want a serious dive watch
The 116660 is a proven performer. It’s been tested in real-world conditions and can handle anything you throw at it. If you’re looking for a solid, no-frills Rolex dive watch, this is a great choice.
Choose the 126660 if:
- You want the modern Caliber 3235 with 70-hour power reserve

The 126660 is the smarter pick for most buyers. It’s more advanced, more comfortable, and holds its value better. Even though it costs more, it offers better long-term benefits.
Ultimately, your choice depends on budget and priorities. But if you can afford it, the 126660 is the better all-around watch.
What About the New 136660?
It’s important to note that both the 116660 and 126660 have been replaced by the ref. 136660, introduced in 2022.
The 136660 keeps the Caliber 3235 movement, 3,900-meter water resistance, and D-Blue dial option, but features a slightly updated design. It’s made from RLX titanium, making it lighter than the steel models.
If you’re buying new from an authorized dealer, you’ll likely get the 136660. But the 116660 and 126660 remain highly sought after on the pre-owned market, especially the D-Blue versions.
So while the 136660 is the current model, the 116660 and 126660 still hold their own—especially for collectors who appreciate their place in Rolex history.
