Founded in 1964

By Chairod Mahadumrongkul, Cosmo Group PLC and our affiliate companies are endowed with more than 58 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 to the year 1964, Mr. Chairod Mahadumrongkul started his COSMO business nearly from scratch. At the time, Cosmo barely had hi-technologies, experts and even market opportunity and did not seem to be able to attract any of the world's most powerful luxury watch brand from Switzerland to become its business partner like what we have seen in the present. We, at Cosmo, have been running our business ethically and honestly. We are always committed to perform our job consciously and deliberately. Thus, in getting our work done, we always start with getting the right understanding

We concentrate on tree core product areas Boxes & displays, watch dials, watch cases & accessories. Our quality standard contributes immensely to being behind leading brands. At COSMO. We harmonize our long experiences and full-scale manufacturing facilities with skillful people, as well as with automation and technology.
