Pre-owned Rolex Sky-Dweller ref. 336239 (2025) marks the first instance in the collection’s history of a White Rolesor model paired with Rolex’s proprietary Oysterflex rubber strap. This strap option initially debuted in the series in 2020 in yellow gold or Everose. As of 2023, collectors also have the option of silvery White Rolesor, which we think looks outstanding paired with a classy white dial, contrasting with the matte black rubber. The Sky-Dweller is famously one of Rolex’s most complex staple collections, boasting a rotatable Ring Command bezel and the caliber 9002 movement, which features a second time zone, month display, date, and stop seconds. The movement is anti-magnetic and shock-resistant, boasting a substantial 72-hour power reserve. Shop Rolex Sky-Dweller Collection
