The watches, glasses, accessories, and jewelry category is a field where extremely high-precision processing technology and aesthetic sense converge. High-precision dimensions and excellent surface quality are required for items such as the minute movement parts of watches, the lightweight yet robust frames of glasses, and the intricate designs of jewelry. The materials used range widely from precious metals, titanium, stainless steel, glass, plastics, and gemstones, each requiring processing tailored to its specific characteristics. Representative processing methods include high-precision cutting, fine grinding and polishing, laser processing (cutting, welding, marking), pressing, casting, and advanced surface treatments such as plating and PVD. A key characteristic is the demand for meticulous tolerance management and an uncompromising commitment to exterior quality to achieve both functionality and decorative appeal.
