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.
