Pre-owned Rolex Sky-Dweller ref 326238 (2021). The collection has come a long way since it debuted back in 2012. Initially, only three models existed, two in full gold (a yellow gold model and a white gold model) and one in Everose and leather. Rolex eventually added leather to all three precious metals, followed by Rolesor models in 2017. By 2020, Oysterflex models had joined the lineup via an Everose model and the yellow gold Rolex 326238 for sale here, featuring a lustrous 18k yellow gold Oyster case and flexible black rubber strap with a titanium and nickel core. Fresh and contemporary, Rolex’s proprietary Oysterflex gives the collection an entirely new look any collectible will find hard to resist. Of course, it’s also got the collection’s innovative Ring Command Bezel and Saros calendar, setting it apart from other offerings in the Rolex dress watch category. Shop Rolex Sky-Dweller Collection
