In 2006, a fifty-percent stake in the American Luminox company was purchased by Mondaine, giving Mondaine increased access to the American market, and Luminox increased access to the European and Asian markets. The speciality of "Luminox watches" is their self-powered luminous readability at night using miniature Tritium devices manufactured by mb-microtec, another Swiss company. In 2016, Mondaine took over the remaining part of the Luminox company and manufactured these watches in Switzerland using the "Swiss made" label. Luminox watches became a major part of revenues for the Mondaine Group in 2020.
