Of the eight watchmakers working in the Hausmann & Co assistance laboratory, a technician deals exclusively with polishing and cleaning cases and bracelets in one of the departments for clocks. All are specialised and licensed by the parent company, where they are periodically updated with specific courses. Trademarks, in fact, for the repair of some complicated watches require a qualification from the factory. This is to prove how important good assistance service is in the overall assessment of a brand. Hausmann & Co Assistance is considered to be of the highest level, with qualifications provided by A. Lange&Söhne, Pater Philippe and Rolex, after difficult training and updates.
