Rolex Sky Dweller — ZF Factory

ZF’s all-new Rolex Sky-Dweller series, known as “the most complicated Rolex in history,” has officially arrived. With refined craftsmanship and the correct adjustment method of the genuine watch, it redefines what a true Sky-Dweller replica should be. The 42mm Oyster case is crafted from 904L stainless steel and faithfully recreates the classic design. It features a highly transparent sapphire crystal, along with a Cyclops lens over the date window. The bezel uses Rolex’s Ring Command fluted bidirectional rotating bezel, and the month function can be adjusted through the rotating bezel. The clasp is an Oyster folding clasp with a 5mm Easylink extension system. ZF’s exclusive genuine-spec dial mold in bright blue sunburst finish shows vivid changes under both sunlight and cloudy conditions, capturing the same spirit as the genuine piece. It is powered by ZF’s exclusive modified 9002 movement, beating at 28,800 vibrations per hour, with a 72-hour power reserve. Like the genuine watch, the correct setting method is centered around the second time zone, which the Sky-Dweller displays through the sub-dial. It consists of two elements: the red inverted triangle located below the logo, which points to the second time zone displayed in 24-hour format. When you rotate the crown and pull it out to the first position, turning it upward adjusts the calendar, while turning it downward adjusts the hour hand independently without moving the minute hand. Pulling it to the second position allows normal time adjustment, and the 24-hour sub-dial ring moves together accordingly.
