Housed in a 42mm Oyster case crafted from White Rolesor — Rolex's combination of Oystersteel and white gold — the Sky-Dweller 336934-0001 features a fluted, bidirectional rotatable Rolex Ring Command bezel. The monobloc middle case pairs with a solid case back and a screw-down Twinlock winding crown, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The green dial offers a Chromalight display with long-lasting blue luminescence for high legibility, while 12 apertures around the dial's circumference indicate the month. An instantaneous annual calendar sits at 3 o'clock alongside a 24-hour off-centre disc for a second time zone. Powering the watch is Calibre 9002 — a perpetual, mechanical, self-winding movement with dual time zones and annual calendar functions, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, and approximately 72 hours of power reserve, rated to -2/+2 seconds per day after casing and COSC certified.
The Oystersteel Oyster bracelet is built from three-piece solid links and fastens with a folding Oysterclasp featuring an Easylink 5mm comfort extension. This example is unworn with stickers and is offered as a complete set with the Rolex box, card, and booklet.
