Very rare chronograph with a movement signed Delba watch and interesting hands. While on the move, all functions work; when the chronograph is reset, the second hand does not become strictly vertical; the photo shows how it stands. Everything else you see in the photo. A ll functions work properly. The watch was not polished, not serviced, the accuracy of the movement and its duration were not measured. A video of the movement and chronograph in operation is available upon request. Good option for a restoration project.
