Rare original “exploding numbers” dial. Solid silver hallmarked case. Dial is completely original and un-restored. Balance wheel turns when given a puff of air. Four screws keep the caseback in place with two of these screws missing. There is also a space between the crown and the case as per the photos. Glass also feels loose and I expect even with the case screws in place it will continue to feel a little loose. Solid silver case measures 24mm wide by 29mm tall. Hundreds of watches in store.
