Rolex Deepsea Sea-Dweller Ref. 126660 Dive Watch

Rolex Deepsea Sea-Dweller Ref. 126660 Dive Watch First Look

Baselworld 2018 is proving to be a busy time for Rolex as they’ve launched a slew of new models, including the newest Rolex Oyster Perpetual Deepsea Sea-Dweller Ref. 126660. Minor changes to the model give it a bit of an update, but the real change is the utilization of Rolex’s new 3235 caliber.

The new Deepsea Sea-Dweller features a number of changes that aren’t immediately apparent and may take someone who owns or is really familiar with the watch to notice. For instance, Rolex “Redesigned” the lugs. Translation: they now feature an apparent, ever-so-slightly rounded taper on the edges instead of simply being flat. Additionally, the bracelet is thickened up by a millimeter or so to accommodate for the slightly thinner lugs due to the taper and the Oysterlock Folding clasp was resized to match.

But the real draw to the new release is that the Sea-Dweller now utilizes Rolex’s new perpetual Calibre 3235 – most popularly used in the Sea-Dweller 126600 unveiled last year. The movement has been largely coveted among Rolex sport watch enthusiasts since it’s the first movement to receive Rolex’s own Superlative Chronometer certification based on their own standards. That may mean if this piece interests you, get on the list now if you want this in your watchbox before the next Avatar movie is released.

Overall, there aren’t too many sweeping changes made to the aesthetics of the model, but I do like the refresh. The Calibre 3235 is going to make this a sought after version of the Sea-Dweller and that will mean widespread availability isn’t likely to happen right out of the gate. Rolex’s sport watches are in high demand, so get in line quick. Price for the Rolex Oyster Perpetual Deepsea Sea-Dweller Ref. 126660 comes in at $12,550.

    This watch is stupid. To each his own but I have a hard time with giant ugly divers that boast useless depth ratings, regardless of branding. The gradient dial is nice but then marred by the paragraph printed on it, and I appreciate the use of green highlight instead of red, but other than that this watch looks like a giant disaster.

    • IanE

      Well, you wouldn’t expect a smartwatch from Rolex!

      • Travis Cannata

        I get it!

      • SuperStrapper

        I might, but they would only update the software every 20 years.

      • Drazen B

        Post of the day!

    • The ‘Ringlock’ nonsense in the chapter ring kills it for me. It’s the ‘Power Reserve’ text of dive watches.

  • SuperStrapper

    I’m no rolex expert but don’t the 3 dots on the crown mean precious metal?

    • Travis Cannata

      TRIPLOCK crown.


      • SuperStrapper

        I get that, I thought 3 equal sized dots meant rollesor and 3 dots where 1 or 2 are bigger meant platinum.

        • Travis Cannata

          I might be wrong, but I think that’s only prior to 2000, and on certain models. IIRC, the current standard is 2 dots for TWINLOCK and 3 dots for TRIPLOCK on their sport watches.

          • Raymond Wilkie

            line = steel or yellow gold twinlock
            two dots = white gold twinlock
            one dot = platinum twinlock
            three small dots = steel or yellow gold triplock
            small.large.small dots = white gold triplock
            large.small.large dots = platinum triplock

          • SuperStrapper

            I think my confusion was the “OR”. I thought the 3 dots was AND, meaning rollesor

          • Travis Cannata

            Raymond coming in clutch!

          • Raymond Wilkie

            Thank you for the ….mond.

    The watch can sink down the ocean as much as it wants, but the date window will still be there floating in the dial.

    In other words, it suffers from the same syndrome the Mark XVIII has: a movement that’s too small for the case.

    • Drazen B

      Now that you mentioned it…


    • Tea Hound

      Rolex do have an excuse for this: the Deepsea case is built to survive pressure at 12,800ft below the surface of the sea. IWC has no such excuse – they just used a tiny crappy movement. Presumably another genius idea from Kern.

  • Playboy Johnny

    Why the deluge of articles in one day?? End of the month, commitments??

    • Travis Cannata

      It’s Baselworld and things get published as they’re announced.

      • Playboy Johnny

        Roger that.

  • Tea Hound

    I have the (now) previous version of this watch, and I can attest how flawlessly it performs in its natural environment under water. It’s difficult for me to give the exact depth I took my Deepsea to, but it must’ve been around 4-5 feet when I jumped off the side a boat when on holiday. Thrilling stuff! Do any other readers have any Rolex-water-submerging-based tales they’d like to share?

    • ProJ

      Not Rolex, but I once dived (?dove) with my (now-sold) IWC Inge to 10 meteres below surface in a swimming pool.

      • Tea Hound

        An excellent tale; keep them coming!

    • Wisco

      I once forgot I was wearing mine at the beach and proceeded to rinse off my feet at the beachside shower. It stood up to the cold splashes superbly,

      • Tea Hound

        Write to Rolex – they will sponsor you.

  • Juan-Antonio Garcia

    Its like the G-65, you know you can, but you won’t.

  • Manualman

    I love the Deepsea and always have since the day it first hit the U.K. for £4750.
    It’s a proper piece of engineering. I love the fact it feels bombproof.
    I’m getting this new one, very much looking forward to hopefully taking delivery in May.

    Owning, and loving, the outgoing DEEPSEA D-Blue model 1166600 version (…as a daily wear for over a year now – much more livable than most say IMHO!) And, having the very detailed Rolex DSSD D-Blue hardback book that I was given be the dealer prior to my purchase there is one interesting detail difference not mentioned by this article here…nor mentioned anywhere else for that matter:

    EASY TO SPOT DIFFERENCE: The Font on the “Ring Lock System” ring has changed to match the Font of word “DEEPSEA” and “SEA-DWELLER”. (on the D-Blue ONLY)

    This will likely be the easiest way to determine which watch you are looking at in the future…the 1166600 (miss matched font) or the 1266600 (matching font) as the lugs are very similar and could be easily overlooked especially if the band has been changed.

    There are other very subtle font changes in the body copy on the face but not as relevant here. Please PM for those differences as desired

    The Gas Company is coming to my house tomorrow and I’ll ask them what gas escape valve means.

    • Tea Hound

      It’s like an anus for watches.

    “Courage”. It takes courage to resist innovation for so very long.
