This Zodiac Aerospace Jet is a true 24 hour watch, with the hands going around the dial only ONCE in a 24 hour period; and was used by pilots in the 60’s and 70’s. The 34mm. steel hermetically sealed case displays very clean original condition. The original multi-coloured dial looks great and retains the original hand set. The manual winding 24 hour movement is accurately keeping time after a very recent cleaning. The ZODIAC signed winding crown is installed. These are very collectible vintage watches.
