Produced by TW, the 2025 new model Blancpain Fifty Fathoms 5100 series features official dimensions of 38mm. It boasts a high-tech satin finish that is bright and glossy, with high hardness that resists discoloration, dirt, and wear. The case and bezel are replicas with a strong three-dimensional feel, ensuring they never fade. The texture is smooth to the touch and gentle on the skin. The crown and pushers have neat engravings, showcasing superlative craftsmanship. The buckle is satin-finished, with meticulous polishing both inside and out. The pin of the buckle has been chamfered from multiple angles, perfectly replicating the details of the authentic product.The movement uses the 9015 movement modified to Cal.1153, featuring gem bearings in the same color as the original, achieving a truly pure hue that makes the movement look authentic at first glance. The one-piece plate not only closely resembles the original in appearance but also offers better protection for the movement, ensuring greater stability. The plate undergoes grinding treatment before chamfering to prevent copper shavings from falling into the movement, which could cause it to stop.The dial features a date display that matches the original size, with 100% Swiss-imported C3 luminous material that offers brightness and longevity close to the authentic model. The watch is 100% tested for waterproofing at three levels before leaving the factory.
