Hair Spring Seems too Tight

Here is the situation. I have successfully repaired and cleaned a Seiko 6139A Pogue Chronograph watch and I can't seem to slow it down. I have now de - magnitized the watch and still I can't seem to slow it down enough. In regulating it, I actually need to push the beat over and tighten up the Hairspring to make sure it runs. This does not seem right. If I set the beat error to 2ms for example, there is not enough play to lengthen the Hairspring and thus slow the watch down. I have examined the Hairspring and still think it is a bit gummed up, even though I did clean it and de magnitize it. This watch was a disaster when I got it as I had use a drumel tool to remove mold from the rotor; for example. Should I be considering a new Hairspring? 3e7ddfca0443ccf38c54689a3b50193b.jpg

I would remove the hairspring and clean it again as you say you still think it is a bit gummed up even a very small amount of dirt and grime can make a huge difference to its performance. As side note are you sure you've locked the hairspring behind the regulator pin.

As others have already suggested the hairspring may just need a clean, id remove the balance and let it soak for 2-3 minutes in some Renata Essence. I find some Seiko hairspring coils sit closer together than their Swiss counterparts so any debris no matter how small can throw things right off, they can be very very fussy ( i actually had same issue recently with a 6139 chrono and i had to clean the balance 3 times before she played ball ).

Also, if after cleaning the watch is still running fast i would verify the mainspring is correct and seated correctly, if it is the wrong spring i.e too strong, then this could be a cause :)

My experience with Seiko hairspring is that if the movement doesn't run or you have to push here and there, it is not a matter of cleaning or demagnetizing rather the hairsping is somehow distorted. Also if you do not have good amplitude and pattern you would be fighting windmills is trying to regulate it. Please post timegrapher pictures.

Hairspring is locked into the regulator pin. I will give it another cleaning, in an ultrasonic cleaner

Check the hairspring collet is central when placed on the balance clock you'll have to remove it from the staff but the hairspring could be out of shape or twisted is it straight and not catching the clock anywhere.

The thing is, Seiko balances are not really made to be taken apart. It's a risky proposition.

Good advice my fellow guitar player, thanks.

      Black coating on shock jewel metal housing

      By Neverenoughwatches · Posted

      I use elma ammoniated H , the jar remains open for around five minutes while i set the basket up clean and spin off the cleaner. The smell doesn't bother me at all, i do this in a 10 by 8  foot room, but i think I'm immune to most environments 🤷‍♂️. I could open a window or a door i guess but watch repair under the influence of toxic fume inhalation adds to the overall experience. ( just joking peeps dont try this at home ).

      Bezel replacement difficulty

      By Simeon · Posted

      The bezel feels slightly loose over the case. There wasn't a gasket but could the crystal be expanded over the lip in the caseback and then the bezel pressed over the crystal?  Actually this sounds like a possibility. This is a great forum. https://www.watchrepairtalk.com/topic/20587-old-orient-case/?do=findComment&comment=173918

      The cleaner smells of ammonia, but it's not too bad; just keep it covered as far as practical.  I use an ultrasonic machine on a kitchen worktop. The rinse does not smell strongly, it's vaguely like paraffin. I did check the safety data sheets before buying it & it's said to be safe in normal use. My dedicated watch cleaning machine is still a work-in-progress; four position linear, based on 1L kilner jars for station spacing, to have a heated dryer in position 4. It uses standard, readily available parts as far as possible to make it easy to reproduce, plus 3D printed bits for the custom parts. (The horizontal drive motor is out at the moment while working on the stepper drive software)

      Citizen Pilot Radio Controlled hour's hand clearance

      By Albyon · Posted

      I disassembled the hands of my Citizen Pilot Super Titanium Radio Controlled AS2031-57E a couple of times.  The second time because on the first attempt i evidently did not push the hour hand well and in practice it was not well fixed and moved receiving even small bumps. After the second attempt everything seems to be ok.  Except that i have the impression that giving a little more sustained blows on the wrist, the hour hand still has a slight movement, in the order of half a second or less. It is a normal, topical and usual thing about this movement, which, i remind you, is exclusively electronically managed, each hand independently, a clearance in the movement that it has of its nature, or it may depend on the hand is not yet well attached to the pin and should perhaps be replaced because the hole has slightly enlarged?

      Balance staff sourcing?

      By Neverenoughwatches · Posted

      This is something a lot of beginners and amateurs struggle with Nev, being able to remove the staff without distorting the hole of a non steel balance wheel. Having the right tools to do this safely  and effectively is not easy. Even with something useful it takes a lot of practice, i spent two days not so long ago practicing cutting away the balance wheel hub of a staff using a 25mm diamond wheel.  I didnt manage to do it once without catching the underside of the wheel.
