Can't slow down my Sekonda

[Waggy]

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.

Think that's maybe where it was updating?

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 ?

Just checked there Ross, if the list is correct waggy setting is about right.

I'm getting quite good with my Sekonda's, although I only work on the Slava 2428 and 2427, as you can see from the 'what's in my wrist' postings. Yours Poljot looks interesting.

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.

Is the mainspring the correct one, too strong that will cause problems with time keeping.

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.
