this is a beautiful IWC electronic tuning fork watch from the 1970s, coming in great condition and with it´s original booklet. The 38mm steelcase seems not to have been polished yet and it´s blue dial is in flawless condition. The IWC caliber 150 is running perfectly as it should, featuring the constantly running and uninterrupted second hand which is a typical feature for the early tuning fork watches. The original users manual for these calibers is a special and rare add on, you won´t find again so quick. The IWC comes with a generic milanese bracelet and a black vintage leatherband.
