The pivot appears to have way too much side shake in the jewel, but I am not sure. It is the only issue I can find in the auto wind train of wheels. The auto wind works but not enough to keep the watch running over about 12 hours. It should wind the watch enough to use more of the 40 hours of reserve. All those parts have been cleaned. The watch run beautifully except for the auto works. Can someone help me confirm whether this could be the issue or if there is another place to look for a reason the watch won't run longer from the automatic winding? Thanks.

Additional information: that wheel runs on three jewels--one for each pivot and a middle one that is at the base of the pinion gear of that wheel. The pivots on the ends are normal, but the middle one has a lot of side shake. Now I am doubting that it is the problem. Advice on where to look for an issue is appreciated.

The middle juwel is huge. It seems very unlikely that there is exceptional wear while the upper and lower pivots are still fine. And a triple bearing needs some play to avoid binding due to coaxial tolerances.

The most critical parts are the reversers. Thay have to be very clean and free of oil (except the pivots).

A lot of clear close-up pictures will probably say more than a 1000 words and you have a better chance that more members may spot the problem(s).

Pictures are easy to attach 😉

The auto works might be providing enough wind but is the mainspring managing to retain it ?

I assume you're suggesting it runs beautifully when you manually wind the watch? So if the watches running beautifully winds nice everything is working then why would it be a mainspring issue? Maybe we need to evaluate your testing procedure in other words if you physically wind up the watch how long does the watch run?

oh and we seem to have a missing background history? in other words did you service the watch was a giving a problem for you service to its etc.

Hello @OldTimer,

I echo what other say, pictures would help a lot.

 

 But let me ask a few questions. I serviced a 3135 just a few weeks ago. 

1.

Is this side shake observed when the automatic works is installed on the movement, or when assessed separately / taken off from the movement?

The 3135-510 driving wheel is effectively held by three jewels. Two in the automatic works - and the third is on the barrel bridge (right next to the ratchet wheel). Is it possible that the driving wheel missed that third jewel on the barrel bridge?  If so, you probably (hopefully!) weren't able to screw down the automatic work fully onto the base movement.

 

2. Another thing to check is the rotor. Is the axle worn? Symptom would be too much up/down movement of the rotor. There should be practically zero play.

 

3. Did you lubricate like this?

      Hour hand won’t go past certain spot when adjusting time forwards

      If the watch is new, just return it to the seller for a refund or replacement.

      Keevo, Welcome to the group ! I'm thinking that you have some damage to the hour, and/ or minute wheel. Possibly just a bent, otherwise damaged, or missing tooth.   Your photo didn't post that I can see. I think you'll have to open it to start really finding the issue. Best, Randy

      Cap jewel with what looks like a circular engraving around the edge

      By mikepilk · Posted

      In cap jewels on several watches I have serviced over the years. I've recently serviced a couple of Longines movements where the cap jewels were colourless. They are a real pain. Without colour they disappear when immersed in any liquid for cleaning 😲 Not necessarily. Cousins do a 10ml bottle for £26 which will last me for years. That's just half the price of a simple Bergeon silicone cushion, so not too expensive 🤣

      Etachron regulation system

      By BobG · Posted

      I wanted to post an update as I have two movements running really well now, 230-250 amplitude , 0.5 and under beat error, and +/-8 seconds or so. I removed the hairspring assembly in order to start over and noticed that the terminal curve between the stud and regulator arm was distorted. The stud was lower than it should be. I massaged the curve to look pretty good and reinstalled it. I followed Alex's video advice, best I could with 10x magnification, and with the regulator arm set in the middle of the curve I adjusted the stud so the spring was centered. I then made sure I could move the regulator arm the entire terminal curve without upsetting the coils. I then put it back on the Timegrapher and began closing down the regulator pins until I saw a change in amplitude which means to me that the pins were now pinching the spring. I opened them slightly and it looks good except I have a 0 on dial down, +3 on dial up but -16 on crown down.  I'm a bit stuck on how to adjust out the positional error. I also noticed a drop in amplitude, 180-200 on crown down. In the other video link I posted at about minute 26 if I remember he adjusts out positional error by manipulating  the regulator pin gap. With crown down the hairspring falls away from the pin and the rate slows so he closes the pins a bit to keep them tighter in crown down position. That means the spring is tighter on dial up as well but then he moved the regulator arm to slow the movement.  There must be some Seiko experts here that have some methods for dialing out positional errors.
