Ralf Tech is a run by a small group of passionate devotees of fine watchmaking. The mission is to create technically accomplished watches without marketing's diktats and also without belonging to a school of thought or a story already written. Moreover, Ralf Tech is probably the only watch brand to have no Marketing Department by choice! Ralf Tech is not intended as a brand for the mass market. You will not find our timepieces in every department store, jewellers' shop chains, airports... you can discover them in true horology connoisseurs shops and watch specialists, you will find them in the locations at the avant-garde of fashion and in those shops for whom being different is a Lifestyle. Authenticity, innovation, experience and independence... Our values are our strength.
