    I was talking about other possible cases and watches, not this one. Just generally saying...

    Also, please be aware that in some cases the movement+dial is removed from the front. Sometimes you have to remove the crown first through a certain technique and then the dial and movement comes out, after the crystal has been lifted, of course.
    Sometimes there's some sort of a chassis that is attached to the movement, dial, crystal and case back and it comes out of the case. Roamer had this system.

    Quartz movements can and certainly should be serviced just like mechanical ones. But we're usually talking about quartz movements that were made to be serviceable (so not the cheap chinese plastic ones...).
    I would say that this one can be serviceable and you could certainly give it a try. I find them a lot more simple than most mechanicals.
    Only wish they were larger in size as it's a fiddly job.
    This type of movement could also require short circuiting it to start.

    I will try to put together a walk-through of the process of dial printing along with creating the plate itself. Honestly I spend more time on the computer designing the dial layout then it takes two create the actual plate or print the dial.

    Wow this is a very nice Slava. First time seeing this type of dial. Wish the hands were a little wider hehe.

    I'm very satisfied with how this dial turned out. I'm building and Elgin pocket watch conversion into wristwatch and wanted a vintage military dial look. 
    I had recently purchased a lume kit but hadn't had the chance to use it yet. I design the dial with bold outlined numerals for the purpose of filling with lume. It really turned out better than I ever hoped!
    The first dial I did turned out very acceptable, except that I had another issue with it and had to start over. I learned quite a bit just from doing that one dial.
    Once I had the printing plate made I repainted the original Elgin dial to a flat white. I then Inked the plate and printed the new dial. Once everything was dry I then slowly added the lume using a 100 - 0 paintbrush which is about the size of a watch Oiler. I went around the dial 4 times adding a layer little by little. I'm very surprised just how much Lume this process adds. The markers have a nice three-dimensional heft to them...

    Hello,
    I would do a direct replacement if you suspect that part, because it does require friction. Also, check to make sure that the drive train is properly seated...these are unusual movements in that there are 4 plate holes, but beside that couple gear you're having trouble with, only THREE should be occupied. I had this same issue where the darn thing was running but no drive gear was engaged because one of the gear was in the wrong place! I've never seen anything like it,but the design permits this error. I have extra coupled gear if you need one. Just send me your ship info via PM. In the mean time, check your gear placement:

    I think the tension on the couple gear is created by the small curved clip that holds it together....probably that curved clipped loses tension over time or with hard use.  The coupled wheel is indeed pictured in the second image that also shows the escape wheel. That coupled wheel gears with the setting wheel (which cannot be removed) on one end, and the drive gears/barrel gears on the other, so it is responsible for transmission of power directly to the hands. I have lots of spare parts, so don't worry about that! I see you live in Europe, so I would just have to determine shipping, which is a small thing.

    By far most watches of this type are friction fitted so I'm sure this one won't be an exception. You should check the cousins website and you'll find there both the crystal (whichever type it may be) and the gasket for it.

    If the old crystal fits well, then measure that and order the same size.

    If it's too tight to fit, then sand the outer perimeter of the crystal to size. You can also bevel the edge where the crystal enters the bevel at 45 degrees, especially if you are using a crystal press to fit as it helps it to slide in initially. 
    For cases with a removable case back, I would try a crystal/case press first. Then use a crystal lifter if that fails. For cases with non-removable case backs such as 1970's Omegas, I would try to use a crystal lift as there's a small risk with using a crystal/case press of damaging the dial or hands.
    For measuring, measure the hole size and rotate the bezel to find the largest point. Add 0.1mm (or you may have to add 0.2mm if that's all that's available). The current crystal may not be original, so it may not be the best reference for size.

    Putting a tension ring crystal on with a claw tool is almost impossible. You need a press. A die that press a little from the outside of the round part of the crystal to make the it bend a little inwards. 
    If the crystal is 31,0 mm and you have a good set of caliper i think a 31,0 would be fine but maybe you should order a 31,1 to. Just to have an option if it doesn't work. Been there done that as they say.

    Chopin got a reaction from rogart63 in Braun quartz ladies watch, hands fell off   
    Yea the crown should be all the way pulled and that's where a button/lever should be.
    It's possible that you managed to pull the movement away from the movement and the dial pushed against the hands and, therefore, 2 fell off.

    The standard ATC should be fine. I found it best not to go more than one size up from the case measurement, and fit it with a case press. The crystal tool didn't work at all.

    I don't know of a resource that gives good details of the standard Sternkreuz crystal dimensions. Even their own catalogue is pretty thin on information for standard crystals http://www.sternkreuz.de/accordion/assets/Sternkreuz_Gesamtkatalog G22.pdf
    As above, ATC looks like it should be fine. Your new crystal will come with a ring, but you may find reusing the old one helpful if the new one doesn't look or fit right. Some crystals come with a split ring so you can file a little away at the join if it won't quite fit in the case.
    You should choose a crystal 0.1mm bigger than the hole in the case. The old one is unlikely to have shrunk due to the tension ring, so this should be a good guide.

    The crystal is almost always a pressure tight fit. If it's glued it's probably is the wrong size. Someone has put a to small crystal in. Give us a picture tomorrow.

    I bought one of these Chinese clones and it was useless. The teeth weren't sharp enough to grasp the acrylic. I tried to sharpen them but the metal was too soft. I ended up buying a second hand Bergeon

    It definitely comes out the front, it looks like it *might* have a rension ring inside, but can't see that clearly from the picture.
    Give it a good push from the inside with your thumb and it will pop out.

    ^^ What Stuart said. Push it out (if it has a removable case back) and look for a tension ring inside the crystal which pops out. If so, replace with Sternkreuz ATC at one size larger (0.1 or 0.2mm) than the measured diameter. You can sometimes re-fit with a case back press (sometimes called a crystal press, but not the type which forces crystals to become concave like a Robur).

    It all depends what type of crystal it is if its a non armoured type then most are held in place with no glue at all they are slightly compressed around the edge when fitting or removing with a tool called a crystal lifter such as the following,
    http://www.ebay.co.uk/itm/Watch-Glass-Fitting-Tool-Dome-Acrylic-Crystal-Plastic-Lifter-Fitter-Lift-Remover-/271265794833?hash=item3f28b38b11:g:pLAAAMXQHeBSG~Qs
    I have both a Bergeon lifter and a cheap chinese one off ebay the chinese one is actually more useful as it opens out further and can be used to fit larger crystals on pocket watches the only time I have had to use crystal cement was when I could not find a crystal of the exact size I needed so had to secure it.
