Pre-owned Rolex Sky-Dweller ref 326238 (2021). In 2020, Rolex upgraded the Sky-Dweller collection to Oysterflex, a rubber strap proprietary to the Crown featuring a flexible nickel and titanium core over-molded with high-performance black elastomer. The 2020 upgrade only included Everose and the yellow gold Rolex 326238 for sale here. Furthermore, this model was initially available in a handful of dial colors, including black, white, and champagne, like this example. The contrast of yellow gold with matte black rubber is sporty and contemporary yet still holds fast to many of the luxurious design elements that made the Sky-Dweller such a show-stopper in the first place, including that rotatable fluted bezel and function-forward dial. This model has since been replaced in favor of the current production ref. 336238. However, you can still find examples on the pre-owned market in excellent secondhand condition.
