And this is why; the movement is completely different from anything else out there. It has a micro regulator similar to the Revue calibre 81, but that is the only similar feature as the movement had been designed from scratch to be an automatic movement.This one is in good condition, but can do with a service.The auto winder mechanism works on the same principle that Seiko uses where the oval rotor cam engages with a fork that has two fingers that drive the intermediate wheel. One might say its a little over constructed, but I think it is very nice.I take the auto winder apart.Now the auto winder bridge is removed I can see how bad the movement needed a service; there is dirt all over the place!Here you can see the bottom plate before taking it apart. I like how the intermediate hour wheel has holes in it to allow oiling the jewel below it.Here you can see the gear train with the bridge removed.There is a funky wigwag intermediate wheel that engages with the crown wheel and the intermediate auto winder wheel. Considering the amount of dirt I’m amazed the watch was running at all.Here the movement is almost completely taken apart.The mainspring is dirty but in good condition so I will clean and use it again.Here the movement has just been taken out of the cleaning basket and it’s ready to be put back together.I have cleaned and lubricated the old mainspring.I start by putting the balance jewels and seeing that the balance swings freely.The movement comes together without any difficulty.I’m happy to see the movement performs great even with the old mainspring.The auto winder mechanism goes back into place.The dial is not perfect, but has a nice patina.Movement back in the case looking great!I can see how this over constructed and expensive movement did not turn out to be a great commercial hit for Revue, but I would say it is a very cool addition to any watch collection.What a beauty!
