This white dial and nail scale Sky-Dweller replica watch pushes Swiss watchmaking craftsmanship to the extreme. The 42mm 904L stainless steel case is precisely processed by German five-axis CNC. Every corner perfectly reproduces the geometric proportions and light and shadow refraction of the original. The pure white dial uses Swiss multi-layer nano-coating technology, which will present a mother-of-pearl iridescent effect under strong light. The three-dimensional nail scale is processed by micron-level 3D laser engraving technology, and the switching accuracy of the red month display window at 12 o'clock reaches the observatory level standard. The patented Ring Command triangular grooved outer ring is equipped with a 72-tooth precision gear system, which seamlessly engages with the improved version of the 9001 movement. The dual time zone adjustment is as accurate and reliable as a Swiss Army knife. The 100-meter water resistance is certified by ISO 764 anti-magnetic, and the Chromalight luminous coating under the double-sided anti-glare sapphire mirror is 35% brighter. Each link of the Oyster strap has been independently pressure tested, and the opening and closing feel of the hidden buckle is exactly the same as the original. This timepiece is not only a masterpiece of precision mechanical art, but also the ultimate wrist weapon for urban elites to conquer the world.
