As a newly established factory, 904L Factory believes that attention to detail is a form of respect toward customers. While many manufacturers currently support this series, 904L Factory stands out due to the watchmaker’s relentless dedication to excellence—after all, great things often come last. The name ‘904L’ originates from the fact that the model 126500 is crafted from 904 steel, officially known as super-austenitic stainless steel, renowned for its exceptional corrosion resistance (commonly referred to as wear resistance), with a density of 8.06 g/cm³. Leveraging its material advantages, 904L Factory maintains strict control over product quality from the source, while precision finishing, polishing, and brushing processes play a crucial role in crafting the final timepiece through a complex manufacturing procedure.
Technology 1: 904L Factory replicates the genuine enamel-white dial, achieving approximately 99% color accuracy after repeated calibration. The rounded indices and luminescent powder filling are indistinguishable from the original.
Technology 2: Printing uses imported glossy ink materials, rendering the font more three-dimensional and full-bodied, nearly identical to the authentic version.
Technology 3: The ceramic bezel features flawless engraved lettering without burrs. Under 100x magnification, the font edges are sharp and clearly defined, with a three-dimensional interior structure. 18K white gold vacuum plating ensures permanent color retention.
Technology 4: Features the latest crown laser engraving design with a three-ring pattern, unlike the older two-ring version. Currently, only 904L Factory has acquired an authentic piece to accurately reproduce the new crown laser marking—an incredibly detailed effort that highlights the complexity involved in replication.
Technology 5: The 4131 movement’s hour, minute, second, and chronograph hands appear nearly identical to those of the previous 4130 model, with only slight differences in stem height; visually, they are almost indistinguishable.
Technology 6: The bracelet and clasp feature an internal ‘dragon-and-phoenix’ logo created using imported femtosecond laser technology. When magnified, the texture and background patterns are highly detailed and clearly reproduced—far beyond the capabilities of standard laser equipment. Customers are encouraged to conduct comparative evaluations.
Technology 7: The entire watch utilizes austenitic 904 steel, including the case back and toothed ring, whose overall shape closely matches the original, all made from genuine 904 steel. Spectroscopic analysis is welcome to verify material composition.
