The Swiss watch manufacturer Henri-Albert Ditisheim took over the company M & E Ditisheim in Saint-Imier with his brothers Charles, Edgar and Hippolyte. In 1889 the company’s name was changed to Albert Ditisheim & Frères and in 1895 it was renamed Henri-Albert Ditisheim at that time, based in La Chaux-de-Fonds. The brand name Marvin was deposited under the direction of Henri-Albert.
