Here are pictures of a Burlington Getty in a nice Burlington glass back case. After cleaning the watch (and fixing a weird problem...see bottom) it ran very nice, but position error was substantial. In the first chart on the left the dial up and dial down positions are fast but similar. The Pendant Left and Pendant Right were fast one way and slow the other. The Pendant Up and Pendant Down were also fast one way and slow the other. With this being a Hunter movement, Pendant Up is 3 o'clock up. After a few hours of poising the balance, the results were as the middle chart depicts. All positions pretty much the same, but fast. This balance does not have timing screws. Moving the regulator to slow produced the right chart. I think I'll leave it as is, since I like to set watches a bit fast. If I wanted to bring the regulator closer to center, I could always add a couple of timing washers.
This watch also had an interesting problem after I got done cleaning it and putting it back together. It would gain a second approximately every minute. While watching it, I noticed the second hand jump about once a minute. Anybody want to guess what the problem turned out to be?

Since Buster and Tom are both on the right track, I'll tell you what it was. The escape wheel somehow got pushed down its arbor and the teeth were just barely catching the pallet jewel. Every once in a while a tooth would miss the pallet jewel and then it would jump. At first I thought I must have put a jewel in upside down, or done something to misalign the escape wheel to pallet jewel position. I finally noticed the gap between the escape wheel pinion and the escape wheel and after pressing it back into place, it centered on the pallet jewels and no more problem.

Thanks Roger, Do Tom and I win the watch If so, Tom gets it first for 6 monthes and then me too Don't get me confused with a repaireman When your question popped up on my computer, I was on the phone with my olde 85 year old repaireman and those were his answers after I asked him[do I still get it for the 2nd 6 monthes] I will let my olde repaireman check it out while I am its caretaker, promise This is one good place!!! I've never had so much fun with my pan.....[never mind] regards, bb

Nice job on a great looking Burlington, Roger.Is that a 19J? I can't read it in the picture.I just picked a similar movement but with a Montgomery dial.Mine does have 2 meantime screws at the end of the balance arms.Apparently some had them and some didn't.

That is a beautiful watch, Roger! And you put it (and yourself!) through it's paces timing it. Glad to hear that you were finally able to get it timed out okay. The dial is gorgeous.
