This black dial and rubber strap Sky-Dweller replica watch perfectly combines Swiss watchmaking craftsmanship with modern sports aesthetics. The 42mm 904L stainless steel case is precisely machined by German five-axis CNC, and each chamfer accurately reproduces the geometric proportions and light and shadow refraction of the original. The deep black dial uses Swiss multi-layer nano-coating technology, which will show a subtle gradient from obsidian black to graphite gray under strong light. The three-dimensional bar scale is processed by micron-level 3D laser engraving technology, and the switching accuracy of the red month display window at 12 o'clock meets the observatory certification standard. The patented Ring Command triangular grooved outer ring is equipped with a 72-tooth precision gear system, which perfectly bites 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. The specially developed fluororubber strap uses NASA-grade material formula, and it still maintains perfect elasticity after 3,000 bending tests, and the hidden buckle opening and closing feel is exactly the same as the original. This timepiece is not only the pinnacle of mechanical craftsmanship, but also the ultimate wrist equipment for urban elites to conquer the business world and the limit.
