      Guys I just received a Master model cleaner and I am going to have to completely rewire the machine. I would like to convert it to a mastermatic be replacing the forward and reverse switch with a time relay circuit. Has anyone done this and if so any guidance would amazing. Thanks.

      I measured my Omega Caliber 1120 through an timegrapher app. (Dial Up, full wind)
      I know the app is not very accurate.

      I checked about +100s/d difference and sharply tilted graph .
      The odd thing is that the bottom part of the graph is not printed every 100+- seconds.(red-colored circle)
      Is this a feature of the timegrapher, or does it indicate abnormal state of movement component?
      Thank you for the comments.

      A vintage Elgin 15/0, Gr 559.  I took it down, cleaned and lubricated it and it is gaining 15 minutes/24 hours.  I have looked at the HS, it appears to be perfect, clean, flat, not magnetized (de-magged the movement X 3 already), and in position between the regulator pins.  Not hung on the center wheel.  Correct mainspring, and balance is not knocking.    I do not remember amplitude, but IIRC, it was above 22 which is O.K. by me with the movement.  Please give me some ideas as to how to correct this.  It doesn't seem like there are enough timing washers in the world to slow this down!

      Hi, my name is Ross. I am a rookie watch enthusiast and I am really puzzled here.
      Could someone explain to me what kind of a problem am I facing with my timegrapher?
      I do two sets of measurements with the same watch (1 day or 6 days apart) and receive vastly different results - to the point of being completely different from what I observe in real life. 
      For example, my timegrapher shows that my watch is running fast (or ahead of time), while in real life I observe that it runs 7 seconds per day behind. I even recorded a video about it so you could see it for yourself: https://youtu.be/mhGzf6aLMlY
      How should I interpret that? Am I doing anything wrong?

      I am working on a vtg. Citizen cal.7520 automatic movement.
      I have put the watch on the timegrapher 
      The graph looks OK but the beat error shows 9.9ms. I presumed that beat error should be around 1.0~2.0 given the shape of the graph.
      Is the beat error actually bad or the timegrapher is wrong??
      Thank you!

    • Yes Spectre6000, we saw more than a few of those. Thanks for answering a two year-old question. That was a first-time sight. 
    • I will be attempting to build a fully functional, cased Elgin size 6s Grade 206 pocket watch. This all began a short while ago, when I watched a video about getting in to watchmaking as a hobbyist in which the watchmaker being interviewed suggested starting with a scrap pocket watch movement, which can be found on the cheap on eBay. I found the ubiquity and low cost of American movements to be counter-intuitive, as I would think 100+ year old watches would be quite valuable. This led me down the rabbit hole of the history of pocket watches, and America's former status as the worldwide leader in production volume of watches. The Watch Flipping through eBay listings for non-running movements I ended up buying an Elgin one for about $20 shipped. Here is a photo of the movement-side, and here is a link to more info on Pocket Watch Database. An interesting thing about this particular piece is the lack of a seconds sub-dial. None of the examples I see online on Pocket Watch Database share that, which is a bit weird to me.   Phase 1: Irresponsibly Hacking Away When the movement first arrived, I decided to just take a stab at taking it apart. I figured, hey, it's a scrap movement that didn't cost me too much money, what's the worst that can happen? Well, I have to say I'm glad I learned the lesson of why NOT to do that, I just wish I'd been maybe a little more careful. As some fine folks here let me know, with a pocket watch or very old vintage movements, unless you're sure what you're dealing with isn't rare or valuable, don't treat it like trash. I went at the movement with the smallest screw drivers I had available and started to take it apart. Here are the mistakes I made: Not releasing the power from the mainspring: parts flew all over the place and I lost the center wheel for a couple weeks until recently I was looking for a fallen screw and came across it on the floor Not taking pictures - there are a couple missing parts from the setting mechanism, so I am a bit unsure about exactly what was originally going on since I didn't do step by step photos (it's also hard to photograph step by step when the whole thing blows up  ) Unscrewing the banking pins not knowing what banking pins are During re-assembly, after trying to set the banking pins so the watch might run, I gave the balance wheel a spin with a toothpick with what I KNEW was too much force, and broke off the impulse jewel - this also is a lesson I knew in theory but learned in practice all too clearly, not to force ANYTHING, and also not to treat any part as if it's scrap or garbage So with all that in mind, and with some insight from the community here which got me reading about the different Elgin models and parts, I've decided to source another identical movement, and a 6s-sized case + movement. Hopefully between the 3 I'll have enough good parts to have a fine working watch. I'd also love to hear anyones thoughts about "switching," I intend to attempt to use all parts from the same grade and model movement. The case I'd be using would probably not have originally contained this movement, as I see lots of 6s pieces w/ case and movement for sale but not with this particular movement.   Note: since the horrific events described above, I've amassed a bunch of tools (most of them cheap versions from eBay) for watchmaking, including a screwdriver set, tweezers, movement holders, parts trays, cleaner with baskets and jars, hand levers, lubricants, Rodico, and probably some more stuff I'm not mentioning. Will be in a bit of a better position to attack this next challenge. Anyway, stay tuned for Phase 2, when I will make what will hopefully a more measured and informed attempt at the build.
    • Thanks weasol been to them all every cal except the one you want. cheers gary
    • Hi All, I came across this pocket watch in a thrift shop. Here are some photos. Can someone tell me if its the real deal? Thanks in advance.  
    • A few minutes after I posted this, I noticed Mark had a video about polishing perspex crystals with brasso. I'll give that a try before I try to replace it.
