This is the first watch I've "rebuilt" but I'm experiencing problems. Its running but its causing my timegrapher to phase in and out during beat auto detect. Any help or guidance would be super appreciated!!! I cleaned it in an ultrasonic bath (using cheap washer with lighter fluid and rubbing alcohol) and then I oiled all the jewel hole with burgeon oil. I made sure that the oil amount was oil enough to reside in the "cup" part of the jewels. The watch runs but it seems to lose its beat and it screws up my readings.... not sure what could be the issue. Anyone have ideas to what and check? Its a bulova 11alacd movement and its pretty clean. No broken pivots anywhere I could see and also all pivots seem to be residing in their respective jewels. i did kink a part of the mainspring towards the end.... not sure if that could cause a hiccup in its beat.... also not sure if perhaps what I am experiencing is banking or knocking.... although I don't hear the signature "gallop" ticking... anyone have any ideas? I also dont have any hands installed on it... not sure if that matters...

Did you clean it assembled? When you say mainspring, do you mean hairspring? That could be it. Or 13 different other things... Did you oil the pallet stones? (you should, lightly) Did you oil the pallet pivots? (shouldn't, but that wouldn't cause your reading)

 

It just takes a piece of dust to cause what you're seeing, or any number of mechanical faults. Next to impossible to say from here.

Hi For the timegrapher to automaticaly record the watch beat it needs a constant frequency from the watch to lock on to the be able to calculate the BPH using its on board crystal oscillator (caliblated) whats happening is it cannot find that frequency or its not stable enough, Due to as NIcklesilver has mentioned to several possibilities he has outlined. difficult to remotely diagnose.  First check the timegrapher on another watch to make sure its working ok, then its down to the watch.

Oscillator can still function correctly if " the kink towards the end of hairspring " is in ,,,end curve,,, section.

Sounds to be running steady and strong.

I sure hope you didn't use this stuff for your oiling!? ;) As @nickelsilver stated; it's basically impossible to tell what's causing the timegrapher readings, and like @watchweasol suggests, make sure the timegrapher is working properly with another watch first. Depending the gravity of the mainspring kink, I guess it could cause some real problems, but I've kinked the inner coil of a few mainsprings a bit while adjusting them (Generale Ressorts) to fit the arbor and haven't had any real problems so far

Servicing and repairing a watch is a delicate process, think brain surgery (without the risk of a patient dying) , and many things can go wrong. You mention the use of oiling the movement and I would assume some Bergeon oil (not Burgeon hair oil). However, use the wrong type of oil or the wrong amount of oil (which you more than likely have and we've all been there) it could have a very negative impact on the running of the watch. I'm in no way affiliated with @Markwho's running this site, but I would definitely recommend www.watchrepairlessons.com. Worth every single penny if you ask me!

Good luck and keeps us updated, We sure wish to help you if we can!

@brenguywow thats awkward i have never seen that. have you tried it in other positions? I just see it in the DU position in the video and in that position you cant see how the balance or escape is functioning. One trick i learned from DeCarle is you can take the movement and press it against your ear. start with your head at a 90 degree angle parallel to the floor (so its movement is in DU), then while holding the movement next to your head, move your head from side to up to other side then back then forward to mimic some of the positions you would use on the timegrapher, while slowly moving your head in all of these positions listen for any inconsistencies in the beat or ticking. This how they did it before timegraphers came out. And it is one of the best ways to detect a positional beat error when technology fails you.

      Hi  in regard to your questions,   The springs should ideally removed from the barrel but to do this you need a mainspring winder that are quite expensive for a one off. Or you c a make your own see Google “ joes mainspring winder”. I have made two and they work well, you will also have to source some tube for the retainers. the gathering pallet cann be removed using levers ( mini crow bars) again I made my own no problem. the case can be glued using evostick wood glue but bind the case together to close the crack. When solid you can use wax sticks (used for furniture) melted and rubbed in to cover any blemish left. best to clean the case and then use bees wax to polish, a bit of elbow grease needed  do not clean the dial with anything other than warm water and a couple of drops of mild soap. Try on an inconspicuous part first. There is a product called MILIPUTTY in various colours on eBay that can be used on cracked enamel dials depending on how bad it is .

      Full plate watch, Suitable tool for adjusting & testing pallet stones?

      By JohnR725 · Posted

      just a reminder about this test is it's not a perfect test it's a quick test. In other words you can adjust the banking pins that are both the same and visually this test will pass everything looks the same but both banking pins can be in the wrong place. although the majority of time when people are playing with banking pins I don't put them in the same place. one of things have to be careful of is I believe some of the pallet fork measuring tools that actually give you the roller jewel size are actually size so that I get confused? What I mean by this is if you inserted a whatever size in and are always told to go a slightly smaller I thought that the gauge itself its number corresponded to give you the exact number. So a lot of it depends upon the gauge itself I think you do want the roller jewel slightly smaller because it does have to fit in the slot and it does have a little bit a play. But if it's too small you will lose energy so does have to be sized right. Oh other things to check is? I'm attaching an Elgin sheet on checking the escapement I've seen references in the past to making sure that the slot in the four corn is nice and smooth and apparently you can end up with a rough slot and then the recommendation is to polisher clean that up. Not sure how well that's really going to work even if it has been the recommendation of other reference materials. yes art full plate watches fun when they don't work. This is where it's nice to have another set of eyes sometimes as maybe they'll find something you didn't  although that can add other issues. The owner of the shop provides himself on his skills of so now two of my watches have relocated to his bench to solve problems both real and imaginary I'm sure that will get fixed eventually hopefully. But still sometimes another set of eyes might see something that you're not. yes this sort of thing can be quite frustrating. Also makes for an interesting problem unless of course you're the one trying to solve the problem that it's a Escapement Elgin setting up the escapement.PDF

      Message board problem

      By JohnR725 · Posted

      For years and I'm still using it I've been using something called SeaMonkey? It's a Mozilla product Basically outscore its Firefox plus an integrated email program. But not the same problems here a lot of times when things are upgraded they tend to be now aimed at very specific browsers like Firefox so I've had to switch to Firefox to respond to any of the messages on the group. So yes they do seem to be getting more browser specific and that may be a reason for others having complications especially if whatever you using hasn't been updated. So yes the world is getting more browser specific perhaps for security reasons. Even though I use a product that is updated on a regular basis is still has problems. So whatever you using for browser should be up to date and if is not recognized it's going to be a problem.
