As a professional manufacturer of custom Damascus steel watch cases, we layer high-carbon steel and 316L stainless steel in a tailored ratio, then forge them at 1200℃ high temperature with spiral torsion and repeat the lamination to form a dense 80-layer structure, with the layer thickness precisely controlled at 0.1-0.3mm. The finished product reaches a Vickers hardness of 320HV, 15% higher than ordinary 316L stainless steel and 40% better in impact resistance. The slight differences in each forging and torsion create a unique flowing cloud-like texture on the watch case, perfectly integrating the industrial precision of metal forging with the natural artistic texture, making each watch case an exquisite craftsmanship work with both mechanical strength and visual beauty.
