Swiss sterling silver cased five (5) minute repeater pocket watch!

Open face case repeating on two gongs - one beneath the other - difficult to see in the video. Operated by the slide in the side of the case. The hours are sounded out on one gong and each elapsed 5 minute period is sounded out on the second gong. Interesting mechanical marvel. Generally it is safest to set the hands in a clockwise motion as some repeater mechanisms do not take kindly to setting counterclockwise.
