Someone really gave those hands a layer of luminous compound! And the rotor is loose in the case.
Movement looks okay besides the rotor being loose. The broken of stem is caught between 2 jewels in the rotor. I align the broken post with the jewel hole and can press both upper and lower jewels out with the staking set. I remove the broken rotor post and press the jewels back in place.Rotor is now fixed and can be used. I can’t get another rotor post that fits the longings rotor. I get a donor Cyma movement to use the rotor post. Longines has modified the rotor construction by having the stem fixed to the automatic winding device whilst Cyma had originally intended for the rotor stem be attached to the oscillating weight. I now see that I can’t use the Longines rotor if I want a working watch. I’m in principle against modifying a movement, but in this case I think it can justified as the Longines actually is based on the Cyma and the modification can easily be corrected if I find a Longines rotor post. On the photo I test if the rotor hole fits the Longines movement.The dial is in fairly good condition, but I will have to do something with those hands.Base plate of the movement, not you can see the groove for the Cyma flex shock protection, but Longines have fitted their own shock protection with transparent cap jewels.I must admit I like this way of fitting a wire spring.Looks like someone has recently serviced this movement, but the watch was not running longer than for 2 hours.Gear train.Lower section of the gear train.New mainspringAfter being cleaned I test that the balance moves freely
Gear train back in the movementAnd I have a ticking movement. The auto winder assembly with the centre jewel in place.Very nice performance on the timegrapher.Just for comparison you can see the rotor post from the oscillating Cyma weight and the rotor post from the Longines movement. The Cyma post is much stronger as the diameter of the post is more than double the thickness.The movement back in the case with a fully working rotor in place.The hands looking much nicer with the old gunk removed and new luminous compound applied.Testing the watch before it goes to my good friend Felix from Sweden.
