Bernard Poitevin worked as a Parisian watch and chronometer maker between 1850 and 1890. He founded the company B. Poitevin & V. Lejeune. His shops were located at Rue Richelieu (1850) and Rue Vivienne 22 (1860-1900). Poitevin produced very fine quality watches with complications like repeater watches, chronographs and first-class chronometers with bulletin from the Geneva Observatory.
