Rolex Deepsea 116660 D-Blue Review

THE FIRST LOOK

Rolex Deepsea 116660 D-Blue First Impressions

What hits you the moment you pick up the original James Cameron.

The first thing you notice about the Rolex Deepsea 116660 D-Blue is that it does not photograph the way it looks in person. Pictures flatten the dial into a flat blue. In the metal, the gradient is alive: a vivid, almost electric blue at twelve o'clock that sinks gradually into total black by six, with that single line of green "DEEPSEA" text cutting across the middle. It is one of the few Rolex watches where the dial does something genuinely theatrical, and the effect only really lands when you tilt it under light and watch the blue catch and fade.

The second thing you notice is the mass. This is a serious slab of steel. Pick it up and the weight registers immediately, the kind of heft that tells you the case was built to survive pressure no human ever will. The brushed and polished Oystersteel throws light cleanly, the Cerachrom bezel is dense and glossy, and the whole thing feels engineered rather than styled. There is no mistaking it for a dress watch or even a regular dive watch. The 116660 announces its purpose before you have read a single spec.

THE WEARING EXPERIENCE

On the Wrist

How the 116660 D-Blue actually wears, day in and day out.

On the wrist, the Rolex Deepsea 116660 wears exactly as big as the numbers suggest, and then a little bigger. The 44mm diameter is only part of the story. It is the 17.7mm thickness and the heft of the Ringlock case that define the experience. This watch sits tall. It catches on shirt cuffs, it pulls a jacket sleeve, and it is impossible to ignore on the wrist. If you have spent your time in 40mm Rolex Submariner territory, the jump in presence here is dramatic.

That said, the balance is better than the spec sheet implies. The weight is centered, not front-heavy, and the Glidelock clasp lets you fine-tune the fit in 2mm steps so the head does not slide around. We would call this a watch for wrists of seven inches and up. Below that, the lug-to-lug and the thickness start to overwhelm, and you will feel the watch wearing you rather than the other way around. Try it on before you commit. The Deepsea is the one Rolex where the measurements genuinely matter, and no amount of online research replaces five minutes with it on your own wrist.

THE DETAILS

Rolex Deepsea 116660 D-Blue Specifications

Case, dial, bezel, and bracelet on the original James Cameron, examined up close.

Case

The Rolex Deepsea 116660 case is the entire reason this watch exists in the form it does. Built around Rolex's patented Ringlock System, it uses a nitrogen-alloyed steel compression ring inside the midcase, a 5.5mm domed sapphire crystal, and a titanium caseback to handle the crushing 3,900 meters of water resistance. The result is a 44mm Oystersteel case that is genuinely over-built. The brushed surfaces on the top of the lugs are clean and the polished flanks are distortion-free, the kind of finishing you expect from Rolex even on a tool watch. The Triplock screw-down crown threads smoothly and seats with a reassuring tightness, and the helium escape valve at nine o'clock is a functional touch the watch never actually needs on land but proudly wears anyway.

Dial and Bezel

The Rolex Deepsea 116660 D-Blue dial is the star, and the reason collectors pay a premium over the black-dial version. The gradient is a true two-tone fade, brilliant blue up top dropping into pure black at the bottom, with the green "DEEPSEA" text providing the only splash of contrast. It is a maxi dial layout, meaning oversized hour markers and a fat Mercedes hands set, all filled with Chromalight that glows a strong, even blue in the dark and holds brightness for hours. Legibility is excellent in every lighting condition. The unidirectional Cerachrom ceramic bezel is virtually scratchproof, with the 60-minute graduations coated in platinum via PVD, and the action is firm with precise, well-defined clicks. There is no Cyclops on the crystal, so the date sits clean at three o'clock without magnification.

Bracelet

The Rolex Deepsea 116660 comes on a solid Oystersteel Oyster bracelet with one of the cleverest clasp systems Rolex makes. It pairs the Glidelock extension, which adds roughly 20mm in 2mm increments without any tools, with the Fliplock extension link that flips out for another 26mm to fit over a dive suit. In daily wear, the Glidelock is the star: it lets you nudge the fit perfectly as your wrist swells through the day. The bracelet on the 116660 is narrower than the one Rolex fitted to the later 126660, and the lug transition is a touch bulkier, which is the main ergonomic tell between the two generations. It is still solid, rattle-free, and built to outlast you.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

What to Check on a Pre-Owned 116660

"On a 116660 D-Blue, the first thing I check is the bezel insert for chips at the edges, since these get knocked around more than people admit. Then I look closely at the dial under a loupe to confirm the gradient and the green text are crisp and original, because this is the dial everyone wants and the dial fakers target. Finally, work the Glidelock through its full range. If it feels gritty or skips, the watch has been worn hard and likely needs a service."

UNDER THE HOOD

Rolex Deepsea 116660 Movement Review

How the movement performs where it matters: on the wrist, every day.

The Rolex Deepsea 116660 runs the Caliber 3135, the workhorse automatic that powered a generation of Rolex sport watches before the 3235 took over. It is chronometer-certified, carries a blue Parachrom hairspring for better shock and temperature resistance, and delivers a 48-hour power reserve. In daily wear it does exactly what a 3135 does in every other watch it has lived in: it runs accurately, holds time well within Rolex's Superlative Chronometer standard of roughly two seconds per day, and asks for nothing. The rotor winds quietly, the crown hand-winds with the smooth, slightly weighted feel Rolex is known for, and the date snaps over cleanly at midnight.

The honest caveat is the 48-hour reserve. Take the 116660 off on Friday night and there is a real chance it is dead by Sunday afternoon, where the later Caliber 3235 in the 126660 would still be running on its 70-hour reserve. For a one-watch owner who wears it daily, this is a non-issue. For someone rotating a collection, it is the single biggest functional reason to consider stepping up a reference. On servicing, budget for a full Rolex or independent service every seven to ten years. The 3135 is one of the most serviceable movements ever made, so parts and expertise are everywhere, and that reliability is a quiet part of the value here.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

Why the 3135 Should Not Scare You Off

"People fixate on the 116660 having the older movement, and I get it, the 70-hour reserve on the newer references is nice. But the Caliber 3135 is the single most proven automatic Rolex ever built. I have sold hundreds of watches running it and they just keep going. If you wear the watch daily, you will never notice the reserve difference, and you will have paid thousands less for the same iconic dial."

MARKET VALUE

Current Market Snapshot

What the 116660 D-Blue costs right now on the secondary market.

The Rolex Deepsea 116660 D-Blue occupies a sweet spot in the James Cameron market: it is the original, it is discontinued, and it is the cheapest way into the gradient dial. Clean examples with box and papers generally trade in the $11,000 to $15,000 range, with the exact number swinging on condition, completeness, and how fresh the service history is. The D-Blue commands a consistent premium over the black-dial 116660, which can be found for a few thousand less. Against its last retail of roughly $12,350, the 116660 has held its value remarkably well for a discontinued sport Rolex.

The 116660 has been gently softening over the past year, down around one percent, in line with the broader cooling at the bottom of the Rolex sport-watch market. For a buyer, that is good news: it is a stable, liquid reference that sells quickly when priced right, with little of the speculative froth that distorts pricing on hotter models. If you want the James Cameron look without paying current-production money, this is the value entry point.

HEAD TO HEAD

How It Compares

The 116660 D-Blue against the alternatives buyers actually cross-shop.

Rolex 116660 vs. Rolex Deepsea 126660 (D-Blue successor)

This is the comparison that matters most for a 116660 shopper. The 126660 replaced the 116660 in 2018 and brought the upgraded Caliber 3235 with its 70-hour power reserve, plus a wider bracelet and redesigned lugs for marginally better comfort. Visually they are nearly identical, both 44mm, both carrying the same gorgeous D-Blue dial. The decision comes down to money and movement: the 126660 costs more and gives you the modern caliber and slightly better ergonomics, while the 116660 saves you a meaningful chunk of cash for what is, on the wrist, an almost indistinguishable experience.

Robertino's Take

"If budget is the priority, buy the 116660 and do not look back. You are getting the exact same James Cameron dial that everyone stops to ask about, for thousands less. If you rotate a collection and the 48-hour reserve genuinely bothers you, then stretch for the 126660. But do not pay the premium for the newer movement and then wear the watch every day, because at that point you have spent extra for a power reserve you will never see."

Rolex 116660 vs. Omega Seamaster Planet Ocean Ultra Deep

Cross-shopping outside Rolex, the natural rival is the Omega Seamaster Planet Ocean Ultra Deep, the watch built to chase the Deepsea's extreme-depth crown. The Omega offers a co-axial Master Chronometer movement with anti-magnetic credentials the Rolex cannot match on paper, plus an even more outrageous depth rating. What the 116660 gives back is the thing money cannot manufacture: that gradient D-Blue dial and the Rolex resale stability. The Omega is the more technically modern watch and a strong value at retail. The Rolex is the icon, and the one that holds its money. Most buyers cross-shopping these two already know which side of that line they fall on.

THE BOTTOM LINE

The Verdict

Is the 116660 D-Blue worth your money?

Yes, the Rolex Deepsea 116660 D-Blue is worth buying, and for the value-focused collector it may be the smartest D-Blue in the entire lineup. It delivers the exact gradient dial that makes the James Cameron famous, the same 3,900-meter Ringlock engineering, and the same commanding wrist presence as the newer references, at the lowest price of any D-Blue Deepsea. The only thing you give up is the longer power reserve of the later movement, and for most owners that is a trade worth making.

This watch is perfect for the buyer with a seven-inch-plus wrist who wants maximum presence and the most distinctive dial Rolex makes in steel, without paying current-production prices. It is not the watch for someone with a smaller wrist, anyone who prizes a slim profile under a cuff, or a collector who needs the 70-hour reserve for a watch in rotation. If that describes you, step up to the 126660. But if you want the icon at the best price, the strongest single reason to buy the 116660 is simple: it is the original James Cameron, and nobody on the street can tell it from the watch that costs thousands more.

Robertino's Take

"The 116660 D-Blue is one of the best value buys in modern Rolex sport watches, full stop. You get the dial everyone wants and the most over-engineered case Rolex makes, for entry-level Deepsea money. It wears big, so try it on first. But if it fits you, this is the one I would tell a friend to buy. It is the original, it holds its value, and it looks like nothing else."
