Inventic was registered as a brand more than 100 years ago – in 1915 – by Fabrique d’Horlogerie Ed. Kummer SA, located in Bettlach, in Switzerland.

Eduard Kummer Bettlach had already been established in 1888. The company was founded by the 43 year old Eduard Kummer and began as a manufacturer of rough movements (ebauches). In the beginning of the century EKB also began to produce finished watches.

Today, the Swiss company is still one of few independent watch brands, producing high quality timepieces with unique design and great value.
