DiW Factory Edition — Integrated Carbon Fiber & DLC Steel Bracelet
The DiW Factory execution of the Nautilus 5711 ‘The Black Grail’ represents a significant technical milestone in replica case construction. By utilizing authentic NTPT thin-layer composite carbon fiber alongside a 316L stainless steel mid-case treated with a deep vacuum Diamond-Like Carbon (DLC) coating, this release solves the structural fragility often seen in full-carbon replicas. The resulting architecture maintains rigorous water resistance and thread integrity while dropping the overall weight to a mere 88 grams.
Powering the timepiece is a deeply customized 324 SC automatic integrated caliber, operating at 28,800 vibrations per hour. Unlike earlier iterations that relied on decorated Miyota bases, this movement features a structurally accurate bridge layout, perlage finishing, and a distinctive gunmetal inertia-block balance wheel. The movement profile allows the case to maintain a remarkably slender 9.2mm thickness.
The matte black dial is meticulously textured with the classic horizontal relief pattern, complemented by blackened hour markers and hands. To maintain the stealth aesthetic, the luminous compound is tinted dark grey, while the date aperture at 3 o’clock utilizes a custom black disc. Every carbon link in the bracelet features unique, layered marble striations, ensuring no two pieces are visually identical.
- Movement: Custom 324 SC Integrated Caliber — Approximately 36 hours
- Case Material: NTPT Forged Carbon & 316L Steel (DLC), 40.0mm diameter, 88g weight
