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 watchmaker’s relentless dedication to excellence—after all, as the saying goes, the best things come last.
The name ‘904L’ originates from the fact that the 126500 model uses 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 product quality from the source, with post-processing techniques such as polishing and brushing playing a crucial role in achieving the final refined appearance. The entire process of crafting the case is intricate and labor-intensive.
Technology 1: The dial replicates genuine enamel white through repeated calibration, achieving a color match of approximately 99% compared to the original. Hour markers are perfectly rounded, and luminescent material filling is indistinguishable from the authentic version.
Technology 2: Printing uses imported glossy ink materials to create numerals with enhanced three-dimensionality and fullness, closely matching the depth and texture of the original.
Technology 3: The ceramic bezel features flawlessly smooth lettering without burrs. Under 100x magnification, font edges are sharp and clearly defined, with inner contours precisely replicated. 18K white gold vacuum electroplating ensures permanent color retention without fading.
Technology 4: The latest crown laser engraving adopts a three-ring design (upgraded from the previous two-ring layout). Currently, only 904L Factory has acquired an authentic sample to accurately reproduce the new crown laser pattern—an incredibly detailed effort that truly honors the craft.
Technology 5: The 4131 movement’s hour, minute, and second chronograph hands show no significant visual difference from the older 4130 model; the only change being a slightly elevated sub-dial, while overall appearance remains nearly identical.
Technology 6: The bracelet clasp features internal dragon-and-phoenix engravings made using imported femtosecond laser equipment. When magnified, the engraved patterns reveal clear striations and textures—far superior to standard laser etching and unmatched by ordinary factories. Customers are encouraged to conduct their own comparisons.
Technology 7: The entire watch—including the case back and gear ring—is crafted from austenitic 904L steel, with shape and proportions nearly identical to the original. We welcome verification via spectrometric analysis to confirm material composition.
