Clean Factory The core craftsmanship focuses on four major aspects: ceramic bezel, fine steel processing, movement adjustment, and dial and clasp details. The overall core objective is “version reproduction + stable quality control”. The following is a detailed explanation of the craftsmanship by modules: 1. Ceramic bezel craftsmanship (core advantage) Raw materials and firing: High-density ceramic powder is used for high-temperature firing, and after molding, CNC precision cutting is performed to ensure that the bezel diameter, tooth pitch, and authenticity are consistent. For popular models such as the Green Ghost, the ceramic color difference is controlled to achieve a similarity of over 95%. For dual-color bezel (such as the Pepsi bezel), the transition is natural with no obvious boundary.
Scale and paint filling: The numbers/scales are precisely molded using molds and then filled with paint, ensuring no paint spillage on the edges and font sizes consistent with the genuine product. Some high-end models feature 18K gold/platinum coating to replicate the original texture.
Night Pearl: It is embedded and reinforced to prevent detachment, with the luminescent material matching the ceramic ring, achieving brightness and durability close to the original.
- Selection of craftsmanship materials for watch case and strap: The main material used is 904L stainless steel (with some basic models using 316L), which is stamped and formed using a 250-ton press to ensure that the density of the steel is consistent with the original, and the weight and feel are close to the authentic product.
CNC machining: The watch case, lugs, and links are all precisely cut by CNC to ensure dimensional tolerances of ≤0.02mm, with seamless fit at the connection between the lugs and the strap.
Polishing treatment: The brushing is delicate and uniform, the polished surface is high-gloss and scratch-free, the edges of the case and the chamfer of the strap are rounded, ensuring no scratching when worn; the gold-plated model adopts PVD in-furnace electroplating, making it resistant to fading.
Clasp craftsmanship: The “CF” logo is laser-engraved on the inner side, with a clear and undistorted logo. The clasp gap is uniform. The extension system of the diving model is consistent with the original, ensuring a high degree of fit when worn. - Movement craftsmanship and movement selection: The main choices are Dandong 3135 / Shanghai 3135 (replica Cal.3135), Dandong GMT movement, and some new models use Shanghai 3235, with functions matching the original version (such as GMT quick adjustment, instant calendar jump).
Calibration standard: After assembly, conduct a 24-hour timekeeping test, with daily error controlled within ±10 seconds. With proper maintenance, it can be optimized to ±5 seconds. The power reserve is approximately 48-70 hours (depending on the movement model).
Stability optimization: Deburring and chamfering are performed on the movement clamping plate, and decorative日内瓦纹 is added to some models to reduce operational noise and enhance durability. - Dial and hands craftsmanship with luminescent treatment: Super-Luminova luminescent powder is used, with a uniform coating and no bubbles, providing long-lasting brightness. In a dark environment, the luminescent color and decay curve are consistent with the original.
Printing and Scale Markings: The dial font and logo are screen-printed, featuring sharp edges and precise alignment; the inner shadow crown can be aligned to 12 o’clock, and the 6 o’clock position coding is consistent with the original format (e.g., 6R****V6).
Pointer craftsmanship: The central shaft of the pointer is of the original “hat-shaped” design, with a natural transition from thick to thin for the second hand. The luminescent filling is full and there is no light leakage or unevenness. - Assembly and quality control assembly process: Assemble step by step according to the original assembly process, with emphasis on controlling the coaxiality of the bezel and case, the alignment accuracy of the GMT hand and scale, and the centering of the calendar window.
Quality control standards: Each watch undergoes waterproof testing (typically ranging from 100 to 300 meters, depending on the model), timekeeping accuracy testing, and appearance detail inspection. Non-conforming products are directly reworked to ensure consistency upon leaving the factory.
