As I am getting close, I would like to know the total thickness of the bezel (top to bottom). I am working on two solutions--one is thinner than the other. The crystal sits pretty proud relative to the bezel, and seems consistent with the pictures I have seen. But, actual measurements would be nice. -
A little bit of superglue and you'll be good to go Although maybe if you had a laser welder you can weld the spring back together. Typically I've only seen it on blued steel Springs and on one occasion a modern spring? The modern watch was a Rolex watch that came and that was literally filled with rust including the barrel was filled with rust in the spring was in a whole bunch of little pieces. I have to wonder if that was an aftermarket mainspring . Then I'm attaching a PDF the Elgin watch company as you can see instigated a study in the 30s find out why mainsprings were breaking. I do though wonder if perhaps there may be a flaw in their study? One other things I wonder about is the metallurgy of the early steel Springs versus the later generation of blued steel Springs whether the metallurgy as part of the problem but in a case they did a study and have attaching a PDF. Because of the study any time I do anything with the blued steel spring when I actually cannot get something that's not blued. Once the spring is cleaned I'm very careful to not to touch the spring with my fingers because I don't want to have a problem with the chemicals on your fingers causing rust and I very carefully get lubrication back on the spring as fast as possible just to avoid these unpleasant situations. Then yes it is interesting one minute you of functional spring and the next minute you have lots of little pieces of spring. For my own personal Elgin pocket watch I put a steel spring and in this happened I'm also guessing that when one layer breaks it sends a cascading shockwave through the spring and that's why it breaks all the way across because after all there is a lot of energy in the spring when it breaks. Oh and my theory on the metallurgy is based on things have improved and for the most part I don't think I've seen a shattered spring in quite some time. Elgin_Mainsprings.PDF -
Hi all A bit of an off chance one but has anyone got any links to suppliers of Conversion cases, to adapt pocket watch movements to wrist watches. I have a couple of movements and bring in the UK there is little chance of finding a replacement case so thought about converting them to wrist watches, I have seen loads of converted watches for sale so there must be a supplier somewhere, anyone know of a supplier. Thanks Paul -
Thank you very much. I routinely harvest these strips so will be able to attempt a repair - much more interesting & potentially satisfying than acquiring a new replacement item. -
Have you ever noticed in the parts list that the hairspring is not available separately? At least typically not available separately. The reason for that is every single hairspring for the most part was specifically vibrated for the balance wheel it is on. So as you can see moving a hairspring from one balance wheel to another does not necessarily work but 15 minutes is definitely manageable If? I see the balance wheel has screws? Providing there really screws in other words you could unscrew them then there is a solution to the problem providing they hairspring actually does fit perfectly in the regulators where it's supposed to be etc. for balance wheels that are running too fast that have screws timing washers can be purchased? Okay the much harder to find than the used to be look on eBay typically a find assortments should be easier for wristwatch size versus pocket watch size. The washers go on as pairs one on each side you do not want to have two washers per screw you ideally want to only have one washer. Typically at least the ones I use are rated in one, two and three minutes per day but despite having a this works for the size it's not an exact you have to try them. Than ours with a few timing washers you could slow this thing down here is an image I found online to show you what it looks like. So basically is unscrew your screw but that little tiny washer on and struck back in again and try not to break the screw head off. Lot of time screws it up and played with before the screws do not like the unscrew and will break off that is very undesirable. Oh and if you would like to get a new skill set you could conceivably find a new collet for your old hairspring carefully unpin it and re-pin it. But that kinda hairspring manipulation is not easy but it could be done.
