Pre-owned Rolex Sky-Dweller 336938 (2023). Rolex updated its most complicated collection, the Sky-Dweller, back in 2023, keeping most of its core design intact while introducing a few upgrades, such as the newer caliber 9002. It also made a few minor changes to the bracelet, primarily the width of the center links and lugs. Keen-eyed collectors will also notice that the seconds hand is thinner, as is the fluted texture on the screw-down crown. While more bracelet options and dial colors have also joined the fold since the model debuted back in 2012, this model keeps it rather classic, with a three-link Oyster in gold to match the case and a sharp black dial. Rolex’s iconic fluted bezel is always fixed. However, on the Sky-Dweller, it rotates and is linked to the movement and crown via a “mechanism of interaction,” as Rolex so eloquently puts it. When the bezel is rotated into place, the wearer can adjust each function on the dial, one by one. An impressive display of Rolex’s watchmaking expertise. Shop Rolex Sky-Dweller Collection
