TW Production 2025 New Model Blancpain Fifty Fathoms 5100 Series Official Size: 38mm. High-tech satin finish, glossy and bright, with high hardness, colorfastness, stain resistance, and wear resistance. The case and bezel are perfectly matched, providing strong three-dimensionality and never fading. The surface feels smooth and is skin-friendly. The crown and pushers feature neat engravings, showcasing superlative craftsmanship. The clasp has a satin finish, with meticulous polishing inside and out. The pin of the clasp is multi-faceted and chamfered for a perfect reproduction of authentic details. The movement uses a modified 9015 movement, adjusted to Cal. 1153, with the color of the jewel bearings matching the original. This truly achieves a pure hue, making the movement appear genuine at first glance. The one-piece movement plate not only looks closer to the original but also offers better protection for the movement, ensuring greater stability. The movement plate is polished before undergoing chamfering, with slow and careful work to prevent copper shavings from falling onto the movement, which could cause it to stop. The dial features a calendar of the correct size, with 100% Swiss-imported C3 luminous material that rivals the brightness and longevity of the authentic product. Waterproof: 100% tested for three levels of waterproofing before leaving the factory.
