Hi, like to put this one to all. I have striped cleaned and put back all parts up to the balance. Checked the piviots on the balance, connected the hair spring, fitted the roller and when fitted into the movement, I can not get it to swing.

Fitted the balance without any parts, put the bridge back and balance spins well. As soon as the roller is fitted and put back into the watch, nothing. Yes I have wound the watch, hair spring is in good order.

The only thing I can think of is there might be a problem with the roller.

Any ideas???????

It might be the safety roller is in the wrong position. When the watch is static i.e. no power and the balance has settled the roller jewel should visually be centred in between the banking pins

With the lever removed does the train run freely when some power is applied?   

 

With the balance removed and some power on the mainspring does the lever snap smartly to the the banking pins when moved with a piece of pegwood?

Hi autowind, thanks for info. The answer to your questions is yes the train runs very smooth and when the balance is removed and a little power supplyed  the pallet does move left and right and the escape wheel moved round. :jig:  I am having second thought about this, I think it might be down to the hairspring catching some where. any thoughts?

      Epilame / Fixodrop

      By Knebo · Posted

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.

      Coil for old Seiko Credor -- 4002920

      There are some parts on Ebay for the seiko 6020A, it may just be a waiting game for someone to strip one down, NOS will be more scarce . K would strip your movement down to the module then start looking at other seiko movement to see if that coil is used, then seek out a seiko part dealer. Also Retrowatches youtube owner Mike may give you some advice try him on his site . He also hangs around amateur watchmaking groups.

      Setting lever spring

      I would agree, in order to work harden something you need to exceed it's yield strength when it moves from the elastic zone to the plastic zone and you get permanent deformation and work hardening which is fairly close to its failure point, relatively speaking and dependent on the material/alloy of course. In theory you can load something constantly within its elastic range and not suffer work hardening issues.

      Probably easier to get a complete new movement - but CousinsUK list it as discontinued. Maybe someone on here knows a substitute movement ?

      Any other thoughts on how I can get a replacement coil? Any “hidden” or unknown physical shops (in Australia or elsewhere) that might have them in stock (but not always online)?
