I like the early 60’s Citizen watches as they made some unusual and funky watches. And this watch is defiantly something special. The watch is in nice condition but could do with a service. I’m not sure about the calibre number; so if there are any Citizen experts out there please enlighten me on the correct calibre number;)Now that is a rotor construction and a half, now you can see why I have been interested in having a closer look at this model.No doubt it needs a service.I start by removing the clamps that hold the rotor in place.Here you can see the auto winder mechanism after removing the auto winder bridge.Down to the base movement.Hands and dial removed.I remove the wire spring that engages with the auto winder ratchet. The wire spring is held in place by the little pin below it.
I remove the setting mechanism.Jewels and crown wheel removed.I have removed the trainbridge and gear train. Note there is not any calibre number only an R. The movement is probably an 1120.I decide to reuse the old mainspring, as it did not look too bad.Balance back in place after cleaning the movement. Citizens ParaShock protection that you also find in the HMT
Base movement almost back in place.Amplitude is nothing spectacular, but it will keep okay time.Setting mechanism going back in place.The Date mechanism back in place.The dial and hands back on the movement.I have put the auto winding mechanism back in place and the movement in the case.The rotor has very nice ball bearing construction.The rotor back on the movement looking good.Case back.I was fortunate to find a diver tension ringed crystal that fitted after a little modification as I could not find any original crystals. It has an Oyster style bezel ring construction where the bezel ring tension keeps the crystal in place. The bezel ring had two cracks and unfortunately one split open. I have silver soldered the bezel ring back together, not that pretty but does the job for now.The overall design is very nice. Unfortunately 38mm case is a little too large for my wrist.
