This replica Sky-Dweller 42 watch interprets Rolex's pinnacle craftsmanship to the extreme - the 42mm 18K white gold case adopts German precision casting technology, and each triangular groove pattern is hand-polished by Swiss watchmakers, presenting a light and shadow effect that is exactly the same as the original. The mint green dial uses Swiss micron-level coating technology, which will present a warm pearl luster under the changing light. The red month display window at 12 o'clock uses laser micro-engraving technology to ensure that the 31-day calendar display switches as accurately and smoothly as a mechanical ballet. The patented triangular groove outer ring has a built-in 72-tooth precision gear set, which perfectly cooperates with the customized 9001 automatic movement to achieve instant adjustment of dual time zones and annual calendar functions. The 100-meter waterproof performance has passed ISO 764 anti-magnetic certification. Under the double-sided anti-glare sapphire crystal mirror, the Chromalight luminous coating and platinum hands form a visual code across time zones. This is not only a precision mechanical artwork on the wrist, but also the ultimate identity symbol for elites to conquer global business travel.
