    Danny We have all been there, know one who isn't highly experienced in watch repair could ever do what you attempted. I believe you have a few choices on where to go from here. 1. Take it to a shop & have your heirloom fixed & serviced. 2. You could put that watch safely away , until you learn how to repair watches. Which you can do right here! You can purchase a basic watch movement & take Marks great course. That's if your really interested in fixing watches , if not go to step 1, there will be setbacks at first (which we all have had) after that the rewards start coming, like how you feel when a watch that was written off as dead scrap comes back to life. I still get that every time. We will be here for back up and encouragement all the way through. we will even tell you the our stories of what not to do. Good luck TimFitz

    Improvised watchmaker's bench

    Two hours of work, pretty happy with the results. I bought two pieces of wood in hobby shop and gave it a try.

    Pocket watch balance poising

    besides the definition of pocket watch can you give us a little more details? Depending upon when the pocket watches made or if it's really low-quality poising really isn't an issue. then if it's an American pocket watch with a bimetallic balance wheel you need to true the balance wheel before poising. It's amazing how much screwed up timekeeping can occur when the arms have been squeezed. Then when you put the roller table back on did you put it in the same position it was found? often times people don't mark where the roller table was and then they wonder why they're having a problem with poise. Then you made the reference to the balance screws being in different positions? did you do anything about that because if the screws are out that screws up the poise. Except you have to be careful you could have mean time screws there supposed to be out although occasionally people don't know what they are and they screw them in nice and tight quite irritating when they do that.

    Molnija pocket watches

    Hy all, I have 2 molnija pocket watches, the older one is a 15 jewel 443, the newer one is maybe a 17-18 jewel and 3602. The 443 is from Cseljabinszk. Prod date maybe 1950-1960, at the back cower are 2 scratches, you can see at the photo, but I draw them to see better. The newer is maybe prod at 1970-1985. Both are working well, but I haven't got the information from the last cleaning, how much were they used... etc. I want to find the origin of my watches and the exact properties. Can anyone help me in this topic? Power reserve Number of jewels Accuracy Production time Reliability Recommended cleaning, if I will use it every day Thank you in advance for your help (Sorry for my bad english, it’s not my mother language.)

    Improvised watchmaker's bench

    I think is pine wood, but not sure. Not an expect, it is kind of soft wood, but not too soft. Bought two pieces of it 100 x 40 x 4 mm and 100 x 5 x 5 mm, it was enough for the bench I made. That looks nice. I was thinking about some place I could put my screwdrivers, but I have only three for now And three tweezers only.

    Improvised watchmaker's bench

    Hello, I recently bought one old sewing box with an idea to make alternative watchmaker's bench which would not take up too much space and which could be mounted on standard desk, so it can be put away when needed. It can be opened from above only, which is a disadvantage, but I always keep all my repair tools in one bigger blue box and take it out during the work anyway (right lower corner), so no need to open and close the box very often. The height of the box is around 5,9 inches (15 cm). My desk has height of around 30,3 inches (77 cm). The height for the work is then around 36 inches (92 cm). According to the commercial products like this here http://www.ofrei.com/page241.html the height of this mini-bench should be around 10 inches (25 cm). Not sure how to raise the bench properly (putting books under it?) and I do not know on which height I should properly work? Another thing is some kind of rail around the box, which could prevent parts from falling down and around the box. Any idea how to make such a thing?

    The above post by Tim Fitz is perfect - a great example of why this forum is different from any other watch forum. It provides the answer to many of the beginner posts here.

    Pocket watch balance poising

    First off we assume that the watch always had the regulator in the zero everything was always perfect it may not have been. If it's been worked on especially the older watches that is the pocket watches things get changed the chance of the regulator going back to zero is almost 0. This is also where I really like before and after timing results which unfortunately can't be done with the balance staff issue. Added weight? If you added weight to poise the roller jewel issue the watch will now run slow. Typically when you're poising your removing weight because that's usually the easiest thing to do. Then the balance wheel is to light you'll have to add timing washers but? before adding timing washers make sure the regulator is back at zero. then the mean time screws in poising? The mean time screw purpose is for regulation I'm attaching a chart. True it's a chart for Hamilton but you can see the effect of moving the screws in it out changes the rate of the watch. so they can be used for tiny poising issues but in a dramatic moving you're going to screw up timekeeping. All of the normal screws need to be in tight not so tight that they break off which they will do occasionally. They need to stay stationary. then depending upon the cleaning machine sometimes they loosen up and they may just a bit loose before. It's always good just to check their down. In a ideal perfect world when restaffing you mark where the hairspring stud is and the roller jewel is. Typically though I do not mark where the hairspring is. If I knew they hairspring stud was where it's supposed to be because the watch was in beat yes but I find it's easier to figure out where they hairspring study is supposed to go by visually verify that the balance is in beat and then putting the hairspring there. then the collet slot it doesn't have to go in any exacting position other than its position determines where the stud goes. On some watches more common on modern the shape of a collet is done for poising purposes.

    I think I'll be needing this soon, so I'm going to print it out. Thanks @RyMoeller. J

    Pocket watch balance poising

    It does not need to be poised accurately to keep good timing in a single position which never moves (think of a platform escapement clock). The purpose of poising is to finely adjust the rate in different positions to keep the timing as consistent as possible. Have a look here, as it should answer all of your questions: http://adjustingvintagewatches.com/dynamic-poising-1-3-basic-tasks/

    Improvised watchmaker's bench

    Your correct I cut the railing because it hurt my forearms. I also made a little rack for my oilers & brush.

    Pocket watch balance poising

    My first tip would be, it’s a pocket watch, so positional error is less of a problem than with wristwatches. I’d put it on the timing machine first if it were me, and see if it needs adjusting at all.

    The gray ring is probably a lead gasket I’d try to get it all out and then measure the slot id and width for a rubber o ring id and cross section.
