Watch the full unboxing
We recently unboxed the Rolex Sky-Dweller reference 336239, the black-dial version in white gold on the Oysterflex strap. Rolex introduced this configuration at Watches and Wonders 2023, and it pairs one of the busier dials in the catalog with a sporty strap that most people assume is rubber. It is not. The Sky-Dweller carries an annual calendar and a second time zone, which puts it among the more complicated watches Rolex builds, and seeing it in solid white gold is a treat. Here is a close look at what came out of the box.

A White Gold Sky-Dweller on Oysterflex
This one measures 42mm, and the entire case and buckle are 18k white gold. The dial is Rolex's bright black, which reads clean against the polished white gold and the flash of the fluted bezel. It is a sporty look on a dressy metal, and the Oysterflex strap leans into that. We think it is one of the sharper Sky-Dweller combinations Rolex offers, and the reaction we get showing it in person backs that up.
At 42mm, the white gold case has real presence in hand.
The Black Dial: Annual Calendar and Second Time Zone
The dial is where the Sky-Dweller earns its name. It runs an annual calendar, so it tracks the length of every month and only needs correcting once a year, at the end of February. The month shows through small apertures set around the dial. A rotating 24-hour disc handles a second time zone, and the date reads at 3 o'clock under the Cyclops magnifier on the crystal.
The hour markers are applied and filled with Rolex's Chromalight display, which glows a long-lasting blue in the dark. Under UV the whole layout lights up, and it is an easy way to see how the markers and hands are laid out.
The off-center 24-hour disc handles the second time zone, with the date at 3.

White Gold Case, Fluted Bezel, and Ring Command
The fluted bezel is not just decoration here. It is a Ring Command bezel, which means it rotates and works with the winding crown to set the watch. Turning the bezel selects what you are adjusting, whether that is the date, the local time, or the reference time on the 24-hour disc. It is a clever way to run an annual calendar and a second time zone without adding pushers to the case.
A scratch-resistant sapphire crystal protects the dial, and the polished white gold flanks and lugs catch the light from every angle.
The fluted bezel doubles as a Ring Command control for setting the watch.

The Oysterflex Bracelet
People see the black strap and assume rubber, but the Oysterflex is built differently. It is a flexible metal blade over-molded with high-performance elastomer. That gives it the robustness of a metal bracelet with the flexibility and comfort of a strap, and it wears great on a warm day. The clasp is a folding Oysterlock safety clasp, and it adjusts easily for a comfortable fit.

Unboxing and Availability
It arrived in the usual green Rolex presentation box, seated on the cushion. The 336239 has been part of the Sky-Dweller line since 2023, and it is a current model. We work the pre-owned and grey market every day, and the white gold Oysterflex version does not come through nearly as often as the steel and Rolesor Sky-Dwellers. If you are after this exact black-dial white gold configuration, it is worth having someone watching for one.
