Hi mark, I came across some watch repair page where one follow the book/traditional way which is winding back a mainspring by hand without using any mainspring winder. I would like to ask you if that's possible? If so, could you make a video on how to? Specifically for the miyota 8200 or dg2813 or maybe any automatic movement just to let me have a rough idea. Reasons for miyota and dg is because I work on those movement more and partly because eta we can buy the whole barrel. Thank you very much. As I have been trying to put back the mainspring by hand but ended up scratching the barrel wall and broke the mainspring. Because as you know this watchmaking hobby is very costly. I'm doing it for a hobby so I couldn't afford owning every single tool. I bought one mainspring winder but I think I bought the wrong one so it ended up lying at a corner collecting dust. Thank you very much. I seriously appreciate it.

It is possible to wind a manul wind main spring, but automatic watch main spring is another thing.

 

I have mainspring winders, but there are times that I hand wind a main spring in old American Pocket watch movements.

 

I would pratice on a large main spring like a old american pocket watch before you try a smaller one like a mens manual wind

watch.

I have done a number in the manner you suggest. Autos and manuals. You start with the end that hooks in the barrel. The initial placement matters in some barrels such as a T end in a pocket watch. Automatics and hole ends that will catch on winding dont matter quite as much. The operation is backwards of unwinding it a half turn at a time by pinching with the fingernails. I believe that was shown in a video somewhere. The trickiest part is getting the first full revolution from the outside wound and pinched in your fingers. After that its not to difficult to wind and pinch a half turn at a time.

remember outside first,arbor end last

      @HectorLooimakes an excellent point, the degree should be brilliant and more than useful but if it's not recognised, then the job options are limited.  You need to find out how many companies are willing to accept Mechrotronics.

      Hi other than testing the coil without the proper tools it will be difficult.  If you +an rig up an external supply and attach it to the cut block you may be able to pick up the pulses on the chip if not on the coil. i have attached the parts sheet for the watch 9362 which gives you the part number of the cut board assembly, whether this part is still available or not , who knows.

      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!
