History

Founded in 1964

By Chairod Mahadumrongkul, Cosmo Group PLC and our affiliate companies are endowed with more than 60 years of experience in manufacturing luxury packaging, display products and technical watch components including watch dials and buckles. During the same period, our Cosmo Swiss Branch was established in Bienne, Switzerland, to provide full sales and technical service of our products for Switzerland and the European markets.

With more than 60 years
of experience

Back in 1964, Mr. Chairod Mahadumrongkul initiated his Cosmo business from the ground up. At that time, Cosmo barely possessed high technologies, experts, or access to market opportunities and did not appear capable of attracting the world's most powerful luxury watch brands from Switzerland to become its business partner, unlike what we observe today. ​

Through our ethical conduct and trusted performance, we focus on three core product areas for the world’s leading brands today (boxes & displays, watch dials, and watch cases & accessories). At Cosmo, we blend our extensive experience and comprehensive manufacturing facilities with skilled personnel, as well as with automation and technology, to ensure the best in class experience for leading brands globally.
