At this year’s Baselworld, Rolex has released a slew of new watches; amongst them is the new updated version of its top of the line dive watch, the Deepsea Sea-Dweller. The new Rolex Oyster Perpetual Deepsea Sea-Dweller Ref. 126660 arrives with quite a few subtle design changes, but more importantly it now features the watchmaker’s cutting-edge caliber 3235 movement. It’s the same movement found in the Sea-Dweller 4000 ref. 126600 launched last year and is packed with technological bells and whistles, including Rolex’s Chronenergy escapement and anti-magnetic nickel-phosphorus construction. It’s also the first movement to receive Rolex’s own Chronometer certification based on their own standards.
In terms of design updates, while the 44mm stainless steel case with a titanium case back remains unchanged, the new Deepsea Sea-Dweller comes with a wider Oyster bracelet and a resized Oysterlock spring-loaded safety clasp. The lugs have also been redesigned. Most of the changes are so minor that they’re hard to notice at the glance. Given the fact that the new caliber is highly coveted amongst Rolex sport watch enthusiasts, it won’t be surprising if the new watch becomes a greatly sought after version of the Sea-Dweller. The Rolex Oyster Perpetual Deepsea Sea-Dweller Ref. 126660 is priced at $12,550.
