Is this hairspring bent?

Hi All

I'm a beginner.  Below are some pics of an Orient H9 hairspring.  It appears lopsided to me but I'm not sure.  The amplitude is about 180.

I've also asked questions about this movement here .  Thank you for any help

It's out of center, check pic for adjustment. The spring should be centered in the regulator when you're done, if it's not, push it right next to the stud to make it centered. The pins (pin and boot) should have a gap of about 1 hairspring thickness, and it should bounce from one to the other evenly when running.

Look at the spring position BETWEEN the regulator pins.  If its central to both pins, I vote to leave it alone.  The old guys (Fried and De Carle) often suggested using a slight bend in the hairspring  to centralize the spring position between regulator pins.  It does appear to be a little eccentric.

 

At any rate, I doubt your slight kink would be a reason for low amplitude.

 

Good luck,

We need a clear picture looking in sideways at the hairspring and balance wheel in the watch.

Then yes technically her out a center but it's minimal it shouldn't be the cause of amplitude problems. They hairspring not flat would be a cause of problems especially when it's touching something.

Can we get timing machine results? And that includes the graphical display with the numbers.

It's hard to get a focused side shot.  It looks level to me.  Though, the focusing may make it appear otherwise.  

I won't have time to work on this again until later next week.  I have a microscope coming and hoping it will help.  

Thank you all.

It looks pretty good to me (Said the idiot that totally trashed a hairspring doing a VERY SIMPLE JOB yesterday).

 

My suggestion would be to look elsewhere for the low amplitude issues BEFORE you even consider touching the HS.    Mainspring, train freedom, dirt, pivots, etc.  HS work is difficult at best.


Good Luck,

d side shot, below.  Looks flat to me.

There is one itsy-bitsy problem with the picture though? It appears to be the balance wheel isn't in the watch?

Yes I know when it's in the watch it's really really hard to see it's easier to see if it's out of the watch but if it's rubbing touching bumping and causing an issue that is usually in the watch not when it's out of the watch. So the problem occurs in the watch that is where you need to look at it. Out of the watch the balance wheel is not in its alignment with both pivots it usually can lean a little bit. So ideally when you're looking at a problem like this you should be looking at it in the watch for the most part.

      Movement inserted from crytal side

      By Jon · Posted

      Put the movement in a movement holder and it will be supported as you push down on the setting lever post to release the winding stem. Make sure the post is over the shoulder of the movement holder so what you are pressing down on is supported. As a general rule, hold the movement and not the movement holder. Replace the hands when the movement isn't in the case and support the centre jewel (if it has one) on a hard surface or staking block when replacing the hands to stop the jewel accidentally moving or even coming out. A dedicated movement holder with a central jewel support is even better, but pricey

      Main spring

      It might help us if we knew which watch like model number.

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.

      Main spring

      By Jon · Posted

      I would go for the dearer spring. You won't need to remove the spring from the carrier ring and then use a mainspring winder to get it into the barrel, for a start. Also that spring is closer to the needed dimensions, especially the length. The length plays a part in the mainsprings strength. If you double the length you will half the force (strength) of the spring and vice-versa. A spring with 20 mm less length would be about 7% shorter, so technically would be 7% more strength, but I find halving this number is closer to real-world findings, so the spring would be about 3 to 4% more strength/force. On a mainspring that ideally kicks out 300 degrees of amplitude, a 3% increase in amplitude would be 309 degrees. Increasing or decreasing the length of the mainspring will affect the power reserve to a greater or lesser degree. It depends how much shorter or longer it is.
