and it's a tricky part sometimes, too.  has to be levered off to be safe.  hand levers work if you don't want to buy a special wheel puller. and when setting the second hand on these, you need to

I can't really answer your last questions , but it seems that you are slowly moving forward in your progress . I tried to find a tech bulletin for a Bulova 11BLC with no luck yet , but I had worked on

I just took my old Weller soldering gun and turned it into a demagnetizer. Passed the watch through a couple of times and then put it to a stopwatch. It looks like I'm gaining 3.25 seconds approximately per minute.

Well I ran it through the Weller de-magnetizer again, opened it up and saw the hairspring looked kind of off center, nudged1285051583671634958327583f2ea785.jpg it this way and that, and now it appears to be keeping good time against a stopwatch. Finally!!!

Could not have finished it without you! Thank you and everyone else that helped walk me through this. I am wearing the watch now and will see how it goes through tomorrow. Now I am still trying to hunt down parts for the Poljot 3105 movement and will be tearing into an 1890 Elgin pocketwatch this weekend!

Well now im getting slightly frustrated. I wore it through the night and when I woke up at around 7:30, it had stopped at just before 7:00. I assumed that maybe it just didnt have a full wind. However, in the last 1 1/2 it has stopped 2-3 times....not sure what could be causing this. I will say that it is not winding easily. I dont know if that is because something is still messed up or because the crown is so small and I can hardly get a grip on it to turn it.

Hey mcass,

My pleasure to help,

I had a similar problem with one of my bulovas. Once I eliminated any issues with hairspring and gears, I decided to replace the mainspring. Bulova has these "lifetime" springs, but they do need to be changed after 40 or more years.

Apparently they were thinking about horses, that's their "lifetime" (lifespan)!! :D

      Hamilton Khaki Mechanical / H-50 winding issues

      By nevenbekriev · Posted

      Hi and welcome. First of all, check the power reserve. If the watch is runing, this means the spring is attached to the barrel arbor. If there is no end of winding, this probably means that the spring is not attached to the barreland it's outer end is slipping. In such case, the watch will run, but the power reserve will be small - about several hours

      Hi welcome to the forum. One can only reiterate the diagnosis already made by clockboy mainspring problem. But before tearing it to pieces take a little time to read the attached file to acquaint yourself with all the various parts. TZIllustratedGlossary.pdf

      B-Dip residue?

      By Geotex · Posted

      We think about these preps as "one-dips" partly because they are terrific solvents but also because the parts they are used on are often cleaner in general than many other parts. But old oils petrify, and even something like B-Dip can't clean up over-soiled parts without some extra effort, as mentioned above. There is an intermediate step during cleaning where the solvent can partially dissolve tarry residues so they have a more liquid varnish-like consistency, and that could well be what you are seeing on the coils after two washes. I wouldn't worry that your B-Dip was contaminated before you used it on this hairspring, but it I wouldn't re-use that aliquot AFTER this cleaning!

      Welcome to the forum, enjoy.. Normally if a hand wound watch does not fully wind ie just keeps winding there is an error with mainspring, either slipping around its winding arbour or the mainspring is broken.

      Most all my 404 candidates are coming from swap meets and "antiques fairs". One more $4US plus battery and elbow grease. Unnamed digital on a decent ss bracelet. Gains 10 seconds a day so not that accurate...
