As a new manufacturing facility, 904L Factory believes that attention to detail is a sign of respect toward our customers. While many manufacturers currently support this series, 904L Factory stands out due to the relentless dedication of its watchmakers to perfecting every product. (As the saying goes, the best things come last.) The name ‘904L’ originates from the fact that the reference 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) and a density of 8.06 g/cm³. Leveraging its material advantages, 904L Factory maintains strict control over raw material quality from the source, while advanced polishing, grinding, and brushing techniques play a crucial role in the production process, which involves complex and meticulous procedures.
Technology 1: The dial replicates the genuine enamel white finish through repeated fine-tuning, achieving approximately 99% accuracy in color matching. The rounded indices and luminescent material filling are indistinguishable from the original.
Technology 2: Printing uses imported glossy ink materials, resulting in numerals and text with enhanced three-dimensionality and fullness, closely mirroring the authentic appearance.
Technology 3: The ceramic bezel features flawlessly embedded characters without burrs. Under 100x magnification, the lettering edges are sharp and clearly defined, with a three-dimensional inner structure. The 18K white gold elements are vacuum electroplated for permanent color retention.
Technology 4: Features the latest crown laser engraving design with a triple-ring pattern, upgrading from the older double-ring version. Currently, only 904L Factory has acquired the genuine model to accurately reproduce this new crown laser marking—an embodiment of extraordinary precision that highlights the effort behind faithful replication.
Technology 5: The 4131 movement’s hour, minute, and second chronograph hands show minimal visual difference compared to the previous 4130 model; the only distinction lies in a slightly elevated pinion, making the overall look nearly identical.
Technology 6: The dragon-and-phoenix logo inside the bracelet clasp is engraved using imported femtosecond laser technology. When magnified, the intricate patterns are clearly visible and highly accurate in reproduction—far beyond the capabilities of standard laser engraving facilities. We invite you to evaluate the results.
Technology 7: The entire watch, including the case back and toothed ring, is made from austenitic 904L steel, with form and composition closely matching the original. Spectroscopic analysis is welcome for material verification.
