This product reproduces the classic design with exquisite craftsmanship, and uses aviation-grade carbon fiber to create the case and bezel. The lightweight material has high strength and is light and comfortable to wear. The dial perfectly restores the matte black texture of the DIW customized version, with laser-engraved three-dimensional hour markers and fluorescent coated hands to ensure clear reading in dark environments. Equipped with a customized Cal.4130 automatic mechanical chronograph movement, it supports precise timing functions and has a kinetic energy reserve of up to 72 hours. The sapphire crystal mirror is scratch-resistant and wear-resistant, and the ceramic chronograph ring has a hardness of level 9. The strap is made of flexible composite carbon fiber material, fits the wrist curve, and is equipped with an exclusive folding buckle. The details reproduce the original brushed and polished process. The entire watch has been tested for 10ATM waterproof, so it is worry-free for daily waterproofing. 1:1 restoration of the real quality, meeting the dual pursuit of quality and cost-effectiveness of high-end players.
