This product is based on the Speedster limited edition. The case is made of aviation-grade carbon fiber and high-strength artificial fiber composite materials. It is both lightweight (25% lighter than the original) and impact-resistant. The bezel has a forged carbon texture with a matte metal texture. The gradient gray matte dial is equipped with a three-dimensional time scale with Super-LumiNova? luminous coating, a red chronograph hand and a Speedster exclusive scale, which is highly recognizable in dark environments. The built-in custom Cal.4130 automatic chronograph movement has an average daily error of ?2 seconds, and the chronograph button feels comparable to the original. The strap innovatively combines carbon fiber skeleton and flexible artificial fiber, and the fit is increased by 30%. It is equipped with a DIW custom folding buckle and laser-etched limited number. The sapphire glass is coated with an anti-glare film, the ceramic chronograph ring has a Mohs hardness of 9, and has been tested for 5ATM waterproof. The details are reproduced with the original brushed/polished double process, and the limited logo is synchronized with the authentic product to meet the collection-level reproduction process requirements.
