UMI Factory has engineered a milestone in high-end watch replication with the Nautilus 5712R, delivering a case weight of 194 grams—identical to the authentic Patek Philippe. This precision extends to case thickness (8.7mm) and strap thickness (2.5mm), with 25 links on the side, preserving the original ultra-thin profile without any compromise.
Revolutionary Copper-Free Tungsten Alloy
Traditional tungsten-copper collectibles often suffer from surface steel coating that flakes within weeks due to thermal expansion and copper oxidation. UMI Factory eliminated this flaw by developing a copper-free tungsten steel alloy, which is harder and more stable. To machine this dense material, they invested in five-axis CNC equipment, and each strap link is hand-polished by master craftsmen to achieve exact tolerances—a labor-intensive process that ensures durability and precision.
Advanced Plating and Swiss PVD Coating
The case undergoes an electroplated nickel base layer, preventing air contact and oxidation, followed by a true gold plating process that matches the original rose gold hue perfectly. This is further enhanced with Swiss PVD coating, the same protective film used by Longines, which adds a transparent, hard shield against wear. As a result, UMI offers a three-year free replacement guarantee if any fading occurs, backed by a gold content detection certificate.
Integrated Cal.240 Movement
The 5712 series features a super integrated Cal.240 PS IRM C LU movement with 265 components, an ultra-thin planar hairspring, and a 21,600 vph oscillation frequency. It replicates all genuine functions: power reserve, lunar phase, calendar, small seconds, and dual quick-adjust buttons. Unlike common fake movement covers, this is a fully functional caliber benchmarked against the original.
Strap, Clasp, and Dial Craftsmanship
The bracelet and clasp are redesigned with deep-engraved logos and an expandable clasp that mimics the genuine's hinge structure, offering a soft, bracelet-like feel. The rotating head pin angle and clasp sound match the original exactly. The iconic beak-shaped case and real center axis of the hands are faithfully reproduced, while the custom gradient brown dial transitions from black to brown under varying light, paired with a sapphire glass moon phase display. Available models include PP5712/1R-001, 5712R-001, 5712G-001, 5724R-001, and 5724G-001.
