Material selection and handling • Substrate composition: high-purity brass as the base material, Ensure the hardness and toughness of the material • Surface treatment: Multi-layer plating process, including underplating , semi-glossy nickel plating and final gold plating • Coating thickness: controlled between 0.3-0.5 microns, Ensures long-lasting color and does not fade easily 2. Structural design characteristics • Double ring nested structure: two ring designs of the same size , one slightly larger than the other, forming an elegant layering • Opening design: with patented sliding closure mechanism, Make sure it is secure and easy to put on and take off • Inner diameter size: accurately controlled at about 58mm, Fits most wrist circumferences 3. Brand identity process • Laser engraving technology: Brand lettering is engraved using high-precision laser equipment • Font restoration: Accurately replicate Hermès' unique sans-serif font, Maintain letter spacing and proportions • Depth control: engraving depth approx. 0.1mm, It is clearly visible without compromising the strength of the metal structure Difficulties in replicating the process 1. Consistency of surface treatment • Difficulty: Achieve the same gloss and texture as the original • Solution: Requires multiple manual polishing processes, Including coarse, fine and mirror finishing • Key Points: Polishing intensity and time control directly affect the final result 2. Exact reproduction of the logo • Difficulties: 1:1 restoration of font shape, size, and spacing • Solution: Use professional measurement tools to obtain original data, Make a special engraving template •Quality control: Each sign must be visually inspected more than 3 times to ensure that there is no deviation 3. Double ring connection structure • Difficulty: Maintain the flatness of the connection without obvious seam feeling • Solution: Adopt precision laser cutting and micro-welding technology • Key indicators: the thickness error of the connection is not more than 0.02mm Key processes 1.
