Watches and Jewellery

Embedding gemstones and coating a precious metals layer on watches and jewellery have become increasingly a norm in the industry. Because of this, jewellery manufacturers, retailers and buyers need cost-effective testing services to ensure their products are up to appropriate standards.

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

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