Watches and Jewellery

Embedding gemstones and coating precious metal layers on watches and jewellery have become increasingly common in the industry. As a result, jewellery manufacturers, retailers, and buyers require cost-effective testing services to ensure their products meet appropriate standards.

ASMAC uses the most advanced equipment to provide the sector with precise and comprehensive analysis, testing jewellery and watch products against specifications commonly adopted in the industry.

Manufacturers rely on our expertise to determine whether their products comply with specific standards, while buyer offices benefit from our timely, independent, and reliable third-party testing solutions to ensure their purchased watches and jewellery meet the expected quality. We also develop innovative methodologies specifically for watch component manufacturers and finishing job shops in the Pearl River Delta region to evaluate new components they develop.
