REVUE THOMMEN AG started as a Swiss watch manufacturer in 1853 founded upon the simple principle of uncompromised precision, quality, accuracy, exactness, excellence and reliability. Today a robust Swiss watchmaker culture prevails in every discipline within THOMMEN raising the meaning of the words "Swiss Made" to new heights.

To quote the Swiss Watch Federation website, "'Swiss Made' embodies a concept of quality that has been forged over centuries". To this day THOMMEN electromechanical instruments are hand crafted by graduate Swiss watchmakers and THOMMEN electronic products are built with the same commitment to quality craftsmanship.
