This replica Sky-Dweller 42 watch fully demonstrates Rolex's pinnacle craftsmanship - the 42mm platinum steel case uses German precision CNC engraving technology, and each groove is hand-polished by Swiss watchmakers, presenting a three-dimensional light and shadow effect that is exactly the same as the original. The pure white dial uses Swiss micron-level coating technology, which will present a unique mother-of-pearl luster under changing light. The red month display window at 12 o'clock uses laser micro-engraving technology to ensure that the 31-day calendar display switch is as accurate and harmonious as a mechanical symphony. The patented triangular grooved 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 water resistance 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 conquering global business travel.
