This product is based on the DIW custom model. The case is made of multi-layer forged carbon fiber, and the matte carbon pattern and impact resistance are comparable to the original. The chocolate-colored gradient dial reproduces the sun-patterned electroplating process, and the light refraction presents a gradient from caramel to dark brown. The time scale is inlaid with Super-LumiNova? luminous coating, and the time is clearly readable in a dark environment. Equipped with a customized Cal.4130 automatic chronograph movement, the column wheel chronograph module is fully synchronized, with an average daily error of ?3 seconds, a 72-hour kinetic energy reserve, and a 1:1 restoration of the chronograph button pressure and reset accuracy. The bezel adopts carbon fiber composite ceramic technology, and the digital scale is filled with platinum plating, with a Mohs hardness of 9 levels of scratch resistance and wear resistance. The sapphire mirror is double-sidedly coated with AR anti-glare film, and the light transmittance is increased by 35%. The nylon strap reproduces the military-standard double-layer weaving process, with an embedded honeycomb breathable layer, and is paired with a titanium alloy DLC-plated black folding buckle, and is engraved with DIW's exclusive laser code. There is a hidden anti-counterfeiting mark at the six o'clock position on the case. It has passed the 15ATM waterproof test and comes with a carbon fiber watch box and warranty card. It is limited to 500 pieces and is a replica of the details with zero flaws. You can experience top-level craftsmanship at only 5% of the original price!
