    Check the balance pivots for wear and the balance jewel cap stones for dirt.
    Do you have a watch machine if so what is the amplitude?
    Of course it could just be a weak mainspring, did it look set when you removed it?

    Some crystals, like the one that is in the video and owned by the OP have absolutely no lip to grab with a lifter. So there is no other choice. Remember that our Mark is not in the business of teaching how to damage watches, but exactly the opposite.

    The hole made the most sense once I realized that the other spot was a bit far from where most releases/detents would be. Good luck with the job.

    The thing is that I loosened that screw near the stem (quite a bit) and it didn't work but I might have to retry.

    Chopin got a reaction from Johnnie in Names of movement parts   
    I know what you mean, sometimes these things are pretty hard to find. It's probably a bit difficult to do this as each movement has it's own type and it's parts and you won't really find one movement to show all types of parts. Here's a couple of images that should help.

    Chopin reacted to AndyHull in Why does this barrel say do not open   
    Here is my tuppence worth. Clean the rest of the watch, re-fit the barrel. See if it works. If so... stick. If not, then, and only then look at how to open the barrel in a non destructive manner. If that is not possible, then you would need to start hunting down those hens for their teeth.
    The only "technical" solution I can think of and this is a worst case solution, if you have absolutely no other option,  would be to very carefully drill two tiny holes in the face of the barrel with a spade drill,  to allow you to flush it out with cleaning fluid, then add a couple of drops of oil. That way you get some cleaning done without killing the thing.

    Chopin got a reaction from DocJo in I'm in shock. Ultrabloc? Hercules? Unisafe? DeSade?   
    Found one of these on a Baumgartner movement (158?) installed in a Sicura.
    It is tricky to work with it but not if you improvise a bit.
    In situations where parts might jump around and get lost I place the movement in a transparent plastic ziplock bag and then work on the movement like that.
    One advantage of the bag is that you can use it like some sort of rodico (minus the sticking part) and press lightly on the components at hand so that they won't move or jump around.
    You can already insert one of the feet into the recess by sliding it in/underneath and when you do that try to position the 2nd foot into the spaced out slot that allows it to fit inside/underneath the incabloc system. Then rotate and do the same with the third.
    That's how I did it.

    You can find cheap usb microscopes for as little as 10$ and they seem good. They don't have a very high resolution but still usable.

    The spring is supposed to hold that small part/pivot next to it in tension which in turn will hold the calendar wheel in splace.
    It'll prevent it from moving in the wrong direction but allow it to rotate in the right direction.

    Chopin reacted to jdm in Seen here first: the new Witshi audio-optical, and PC analyzers   
    The Witschi representatives in Hong Kong are really nice people, today I visited their booth at the Hong Kong Watch & Clock fair and they gladly showed my the first ever analyzer using optical data acquisition (as well acoustic), the Wisioscope S. The balance wheel movement is captured by a lens ans sendors, that works even the movement is in a plastic case. After processing it's displayed together with the audio in an "overlapped" format using different colors for the two channels.

    In an another display mode (I suppose there are even more) the display shows frame-by-frame images from the high-speed camera for visual analysis, I suppose to diagnose issue like pallets depth, lift angle. The machine is hence able to accurately display the latter for any watch mov.t.

    The apparatus is meant for manufacturer's R&D centers, and cost in excess of 10,000 CHF.
     The other new product is their PC-based timegrapher, called CronoMaster. Sorry, no pictures for this one, physically it consist of a nice multi-position mic with USB interface for a Windows PC or tablet. I haven't played much it but it looked nice enough. Full specs and screenshots on their websites. Cost is about 2,000 CHF.

    Chopin reacted to gmoodyii in My first balance staff!   
    Finally got around to cutting my first successful balance staff. It is for a 201 caliber Jaeger-LeCoultre 8-Day aircraft clock. In fact this is the same clock that got me interested in watch repair as a hobby.
    The first attempt resulted in a pivot being cut off while I was finishing it up, it was complete except for the finishing on the last pivot and it just disappeared. That was with wire rod. Second attempt was with blued wire rod, which I should have been using to begin with. Took my time and ended up with a usable staff.
    Installed on the balance assembly and it worked!!

    Chopin reacted to Endeavor in Servicing LACO 503 & 501   
    Hello All;
    Got myself three 1950's N.O.S. "Rolled"-Gold Ladies watches from the famous German watch-company LACO.

    First I like to share some of the LACO watches history;
    In an attempt to make the German watch-industry independent of the Swiss movement manufactures , Eric Lacher founded in 1933 DUROWE. Eric was the son of Frieda Lacher, the co-founder of the German watchmaker Lacher & Co, or "LACO".
    Eric intended to not only supply LACO with his DUROWE movements, but other German watchmakers as well. DUROWE grew strongly in the 1930s, with the number of movements produced peaking at 30,000 per month until the outbreak of the Second World War. During the war, DUROWE continued to manufacture movements, in particular the large chronometer-grade movements used in the Beobachtungsuhren (B-Uhr) commissioned by the German government for use by the Luftwaffe, of which LACO was one of five manufacturers.
    These "Beobachtungsuhren" became very sought-after and are now commanding high prices;

    Not that I have any of those B-Uhren to service here, but just the fact that DUROWE / LACO was choosen as one the five manufactures to make aviation watches, tells us something about the watch quality they were producing.
    The DUROWE factory was situated in Pforzheim and was, just like the KASPER factory, leveled with the ground at the end of WW2. However, DUROWE and Laco had recommenced production by 1949. With the assistance of the Marshall plan, a five-story building to house the Laco and DUROWE operations was built which housed more than 1,400 workers by the middle of the 1950s. Production of movements rose to 80,000 per month.
    The LACO ladies watches I'm going to service are from this period. All the three watch housing and bracelets are made from "Rolled-gold", 20 microns, are brand new (NOS) and are in excellent cosmetic condition. None of the movements do run, however they seem to be intact. Two of the watches do have the 16-jewels DUROWE / LACO 503 movement and one has the DUROWE / LACO 501 movement, which has no jewels. Clearly the 16-jewels movements are of high quality finishing. All the screws do have a high polished finish, so does the top of the ratchet-wheel and trans-wheel. Both wheels do have an immaculate polished "hollow-disc-like" finish. The 503 and 501 are in build-up identical, so I'm only going to describe the servicing of the 503 movement.


    All the watches do have a hinged back-lid in which the movement houses;

    With the back-lid hinged open, the movement can be taken out;

    The hands came off without problems;

    Around the movement sits a "case", more like a case-ring. The ring has a tube soldered on the side through which the winding-stem runs. The movement itself is held in this ring by two case-screws;

    With the winding stem pulled and the case-screws removed, the movement comes out at the front. Clear to see on this picture is the highly polished finish of the ratchet-wheel.

    Once the movement is out, the dial, secured by two dial screws, can be removed;

    This movement fitted much better in my Bergeon 4039 movement holder than the similar shape Kasper 200 movement. Removed the balance and pallet bridge, but the pallet-fork self was "stuck", that is to say that it was able to swivel from left to right and vv, but I couldn't lift it out of its jewel.

    I decided to dismantle the movement to the point that I could submerge it in Zippo lighter-fluid, letting the oil, which was holding the pallet-fork, dissolve.
    Wheel train bridge off;

    Now I could remove the 4th wheel and the escape wheel. The 3rd wheel was underneath the center-wheel, so I had to flip the movement over to pull the cannon-pinion with the pallet-fork still in situ. Removed the cannon-pinion which left me with the main-plate and the "stuck" pallet-fork;

    A part of the keyless works was still attached to the main-plate, but that couldn't harm. Left it all a hour soaking;

    and the pallet-fork came free
    Removed the rest of the keyless works;

    Took the main-spring out the barrel;

    and the balance cap-stone off the main-plate;

    All the parts are now submerged in Zippo lighter fluid and tomorrow it will be the cleaning of the jewels, cleaning & oiling of the balance cap-stones and hopefully the reassembling........ if all goes well !?
    To be continued ......

    Some are screw in while others are press fit. This might be easy to find, you just have to get the dimensions right. A watchmaker should sort this one out.

    Chopin reacted to JerseyMo in Timex Assortment #53 Display Case   
    A few weeks back I spotted a unique display case from Timex history on Ebay.  Yes, it was the 1959 display case where a watch is dropped on and anvil to show how good the watches are shock proof.
    Now what made this even better is that I already had the catalog page showing this case. So of course I had to buy it.  Main issue was that the mechanism that raised and lowered the watch was missing perhaps the most important part.  Which was the  part that would trip the lever.  With a little bit of consultation with a my watchmaker friend a plan was drawn up on how to make the missing part.  So with a bit of spring wire solder to a hex nut and some chain, the display is back in working order.   Now the next one on the grail list is a display that dips a watch in water to show they are water proof.

    Chopin reacted to dieale2 in Things I learnt the hard way   
    I been at this for about a year and I learnt a lot of things the hard way. I don't see any thread about lessons learn the hard way so I'll start here.
    Tea leave holders are not good parts holders. The two halves don't clamp down hard enough and small parts will slip through. Hairsprings are hard. Mainsprings are fragile. Just because someone been in business for 40 years doesn't mean they can't mislead you about vintage watches. Do you homework and don't only take the seller's word. If you don't know what an expensive vintage watch supposed to look like, don't buy it.  You will not save money by buying a bunch of "cheap" watches. You can't (or shouldn't) oil a watch with a single oil and grease. Organizing a lot of parts is hard.

    Chopin reacted to VWatchie in Vostok Generalskie   
    Finally finished my Vostok Generalskie extensive overhaul:





    No other watch have I serviced, cleaned, polished, and lubricated as meticulously as this Vostok Generalskie; the movement, case, dial, hands, and crystal. Case and crown gaskets were of course replaced and silicone greased. I even cleaned and polished all train wheels by hand (a bit over the top, I know, but I just couldn’t help myself).
    I had many good reasons to be thorough though; This Generalskie was a spontaneous gift to me from someone who made a deep impression on me (I’ll always remember you T). I think it’s one of the most impressive looking Vostoks I’ve seen, and I just love that dolphin case back lid. And, it was my first serious attempt to (somewhat) understand and successfully service a 31 jewel automatic watch.
    The service spawned some pretty interesting discussions on WUS and watchrepairtalk.com. First, it was established by our "comrade" experts over at WUS in the “Q&A Expertise thread: Is this watch legit or a Franken?” that it is indeed legit. The first and major challenge for me was to understand how to service the automatic mainspring barrel. As I learned, this is not entirely trivial when it comes to automatic watches (thank you all!). Secondly, I was puzzled by the state of the reversing wheels and how to lubricate them. This too was eventually sorted out.
    For my personal use, I made a "reassembly plan" using pictures from the disassembly. It was only meant for me personally, but for anyone interested click here. I should mention that during the assembly I figured out that it would be most convenient to assemble the parts for the automatic winding as late as possible, so this does not show in my "reassembly plan".
    The quality of the movement and the entire watch is the best I’ve seen in any Vostok, Raketa, or Poljot so far. The movement contained some surprising details I haven’t seen before. The centre wheel held a very small (micro) brass cylinder right in the centre of the arbor to hold or guide the seconds hand pivot (see the picture below). Let me tell you, it was not easy to handle, not even with my finest tweezers. Most shims, like under the balance cock, were gilded, and so on. I believe this watch was meant for export and made to impress. It was sold in Stockholm, Sweden sometime in the early 90-ties.

    I wear it with pride!
