Can't slow down my Sekonda

Good day everyone - I have an issue with my sekonda 2614.2H. I am trying to regulate it, but I can't get it below +300 s/d. I have the adjustment arm as far as I can, but still +300 s/d.

I've demagmetized it several times and checked the coils and they appear to be clean and not touching and concentric and not wanting to stick together. When watching it run the coils seem to breath nicely and not stick and are centred well, see pictures:

I'm probably missing something obvious - any help advice is appreciated

The line under the amplitude reading is disjointed, I've tried the timegrapher charts but I don't know what that means. 

When the graphical display reaches the other side it wraps around and continues over again. They gap is the gap between the old versus the new basically.

Then just because I like to see other pictures there's a link below for your watch

Then the pictures are showing what I want to see. You're running fast even though the regulators on slow I wonder if they hairspring is touching anything it's not supposed to. This is where a angle shot would be nice like aimed at the regulator so we can see if the inner coil of the hairspring is may be bumping on the backside of the regulator the same as where the stud is you want to make sure they're far enough away and not touching. I just can't tell what the pictures

then what happens if you rotate the microphone to a crown down position just because I'm curious

I think your lift angle might be wrong matey, my 2609 ha is 42° check this setting then start again with your readings.

Watchguy does list the 2614 as 51 ° so you are pretty close.

Have you verified the timing manually as well ?

Thanks all for the comments, I wasn't getting notified that there were new ones so apologies for not responding. I'll take some more pictures tonight and get back to you on the questions above.

Novice here, could you please elaborate? I can't imagine how a stronger mainspring could have such a drastic effect on rate. That's assuming the balance isn't knocking though.

Watching it run isn't good enough.

To enhance your spotting- ablity , take a video of its running, watch it in slow-mo , most likely its intermitent sticking.

Good luck

I replaced the same mainspring, so I  assumed it was the correct one (hmmm assume = ass out of you and me). But this was a non-runner so I can't be sure if it was causing the same issue before I worked on it, worth looking at.

      Reusing mainsprings in an automatic and slipping

      By JohnL · Posted

      Ah, well there is the rub. I ordered a post and oscillating weight, but clicked on the wrong thing when adding the weight to the basket adding an automatic bridge. Ordered a weight, and it's somewhere in the ether after our customs and excise folks rejected it because of the documentation.  Yes, both springs inserted the same. "Is the idler gear ok", and here's why I posted to the newbie area: So, reading between the lines, and again correct me if I'm wrong here, the automatic winding mechanism will have an ideler gear, along with the reverse wheels, that prevents over-winding? There is nothing (that I'm aware of) between the crown pinion, crown wheel, and the ratchet wheels to prevent over-winding other than the mainsprings slipping in the barrels.  This is only the second automatic I've worked on. The other, a Vostok, had a very obvious mechanism.  I shall look at the automatic winding mechanism in a bit more detail when I've a bit more time. At the moment I'm taking a glance here now and then when work is dragging 😉 As ever, thank you for your help. Always appreciated.

      If the weight was worn how does the post look as normally you'd have to replace both. There should be no real resistance at the end and just be able to keep on winding. Did you insert both springs the same and is the idler gear OK.

      Assembled and running well, I'm asking after the fact. I'm waiting on a new oscillating weight as this one was worn (they have a reputation for it apparently, no bearings). So I've been winding it by hand, but meeting quite a bit of resistance at the end, more than I think an automatic weight will overcome. It's not quite as sudden as a manual mechanism, but there's very little in it, certainly enough that I would be concerned about breaking something if I continued.

      Loose pinion

      By mbwatch · Posted

      Remove the cannon pinion from the dial side first. The "clip" you describe is sort of a metal tab some American companies designed their cannon pinions with in order to make it easier to tighten friction. If that is the problem, the solution is as simple as gently squeezing the tab with tweezers to bend it ever so slightly inward, while supporting the inside of the cannon pinion if possible (it may be harder to support inside since it does not have an open tip as a hollow tube) The cannon pinion should just pull straight off of the arbor on the dial side if you pull it straight up with tweezers. There's no jewel in danger of breaking and the arbor is thick so there isn't much risk of breaking the arbor. But when you are describing that the center wheel's pinion is not turning the arbor, is the pinion firmly attached to the center wheel? If you remove the center wheel and hold onto the rim of the wheel, does the pinion turn independently of the rest of the wheel? It should not.  I'm not sure if this was the case on older Waltham, but the pinion may be threaded onto the center wheel arbor and they are often loose. This was a safety mechanism for a broken mainspring and may just need to be tightened back down. I can't remember for sure, but these might be a reverse (left) thread instead of normal right. And does the entire arbor turn independently of the wheel? Also should not.

      You may get some extra friction on the barrel lid so may not slip as easy but I wouldn't think it's a problem. My suggestion would be to finish the assembly and see how it runs.
