    eta 2784 question

    I agree, shortcuts often turn out to be the long way of doing things. As the old adage goes, check it twice, fix it once, or to put it another way, you need to fully understand a problem before you can resolve it.

    eta 2784 question

    Agreed. At some stage, you are going to have to bite the bullet and take a look at the spring, whether it is the old one, or the replacement. Besides it may be a simple fix, so you might not need to stump up for one or other or both of the barrel and/or the spring. I guess it could be simply that everything is so gummed up with old oil and dirt, that the spring simply isn't catching on the barrel. Alternatively, it might only take two minutes with a sharp file to fix the issue. Furthermore, in the extremely unlikely event that you do take an eye out with the spring, whats the problem? You can still see to type "I told you so" with the one remaining good one.

    That is certainly an option. They should be available, and hopefully not eye wateringly expensive either, however it may be possible to fix the one you have. Just put on your safety specs and crack it open. I think a 2770 series barrel and mainspring would be correct, but check before you purchase. Something like this perhaps - https://www.ebay.co.uk/itm/ETA-Calibre-2770-Part-182-Complete-Barrel/222524899179?hash=item33cf847f6b:g:NLkAAOSw4CFYwvVt Also confirm with the supplier that it includes the spring.

If you have ever wondered what is going on inside one of those infernal kwarts thingamabobs, this article might be of interest. https://zeptobars.com/en/read/Luch-quartz-wristwatch-IC-at-sc-tuning-fork The full article is here -> https://3.14.by/en/read/quartz-wristwatch-watch-ic-decapsulation#fun One point he skips over is the "16-stage divider", this doesn't divide by 16, it divides by 2^16 (or 32768) to give us our one second time reference. I still prefer a well engineered mechanical watch, but you have got to admit, there is something quite captivating about that die shot.

    I'm not quite sure what to make of this (pun intended), but I'm sure there will be a few o-pinions round here. https://www.ebay.co.uk/itm/Newly-Cool-Punk-3D-Metal-Machinery-Gear-Nail-Art-Tips-Gold-Charms-DIY-Decoration/162480889276?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 Maybe a source of random cheap spare parts? I came across the seller while looking to see if anybody sold anything suitable for use as hour markers on a messed up dial.
  6. Hello from Scotland. I recently re-awakened an interest from my youth in watches and clocks. Strangely the catalyst was searching for a replacement hand for a Starrett dial indicator that I picked up for pennies on ebay and which I though might be useful for leveling the bed on my 3d printer. It was missing the dial hand, which looked very like a watch second hand, so that led to a search for a suitable donor watch. Needless to say I then got distracted by the vast array of old time pieces to be had for pennies, and grabbed a couple of basket cases. The first one was a Sicura Voyageur. It only says Voyageur on the dial, but it has all the hallmarks of a Sicura, with the seahorse emblem on the caseback, and the remains of hands that look like the Sicura "Marine Star" It was in a sorry state, but after a quick clean, polish and minor overhaul it's Rondo-matic heart is now ticking away nicely. I'm awaiting a suitable second hand for that, currently on the slow boat from China, and it has parted company with its bezel, which I may fabricate a replacement for if I get the time. The problem there is that I can't find another "Voyager" to compare with, and Sicuras had a variety of different bezels. I found WRT by watching some of Mark's many excellent Watch Repair Channel videos, many thanks for those Mark. I have a couple of other basket case watches ordered from ebay. I set myself an artificial ceiling of £4.04 per watch (although I have already blown that a couple of times), as I figured that there was a lot of fun to be had from resurrecting an item destined for landfill and costing less than a trip to the coffee shop. My day job involves computers, and I dabble in electronics as a hobby, which means I'm fairly patient, and used to dealing with very small fiddly components, and already have a bunch of small tweezers, screwdrivers, clamps, magnifiers and so on.

    Revisiting an old hobby

    Something has been bothering me. Why is it that the Chinese manufacturers don't produce a "classical" mechanical watch, of reasonable quality, say similar to the HMT or maybe the F Hinds I showed previously both of which in my opinion are actually pretty good for what they are. All they seem to produce are novelty skeleton watches in garish oversized cases. I know the current trend is for large copper frying pans generally, but there is still a market for classic elegance at a reasonable price. The closest I can find would be something like this.. https://www.ebay.co.uk/itm/Casual-Men-Fashion-Automatic-Mechanical-Stainless-Steel-Date-Analog-Wrist-Watch/113180346586?hash=item1a5a1308da:m:mTe9V3zssTANPTKXOzCBeVg:rk:38:pf:0 But I am looking for something more "classical" than that, and not with a 24 foot wide strap either. They do seem to make some reasonable quartz designs, but nothing automatic or even 17 jewel manual. Its not as if the movements they produce are particularly huge, or invariably of poor quality (thought undoubtedly some are), since a number of non Chinese manufacturers do make well designed timepieces with these, or similar movements. Given the recent advances in manufacturing, it should be possible to produce some very high quality designs without having to charge a fortune for them. Maybe there is a marketing opportunity being missed here. Does anybody know of any current Chinese brand that produces watches you might actually want to wear, with the quality at a level of say Citizen, Seiko or even Sekonda, but with the attractive price tag that generally comes from being Chinese?

    OK I can forgive those, they are a work of art... More here -> https://struckcontemporary.com/collections/vendors?q=DAN+TANENBAUM ... although if I had the money for one of those, I'd probably rather spend it in some real watches.

    eta 2784 question

    If the whole barrel is slipping, you can possibly spot that without stripping the thing down. I have an old EB8800 that makes similar noises, in my parts pile, and I know why it misbehaves, because I can see the barrel spinning rapidly when I wind it more than a few turns, because the whole barrel lifts up at one side as it is wound. The cause is a broken hold down screw on the rather flimsy barrel bridge. The screw head is missing in that mech, and the shaft of the screw is still in the base plate, which is why I haven't bothered fixing it yet, as I haven't had the time or inclination to try to extract it yet. The EB880 is a pretty basic mechanism, as you can see, and this seems to be a known weakness in that particular setup. It is also much easier to see the barrel in that case, because it is staring you in the face. The picture above is of a similar (pin lever, rather than jeweled, but working) EB8800 with two unbroken screws, so you can understand what I am talking about. Watching the barrel on your watch might be a little more tricky. Having said all that, even if you do spot the barrel slipping, you will still need to strip things down to figure out why.

    eta 2784 question

    The most likely parts are the barrel, the barrel arbor and/or the mainspring, but you wont know which until you inspect them closely. It could also be that there is play in the barrel bearings or movement in the plate(s) holding the barrel in place (a broken screw perhaps), allowing the barrel to rock or slip when there is sufficient tension in the spring. My money is on the mainspring, but I'm usually wrong.

    I believe so, but the nail art in the ebay listing shows real watch parts. I presume you will actually be shipped some cheap imitations however. I did recently see something similar in the form of earrings in one of the pricey art galleries in Perth, which were also made out of real watch parts. I'm somewhat ambivalent about the whole thing. Yes it does look interesting, but someone wrecked a watch movement to make it.

    You could of course replace the selenium rectifiers with modern silicone diodes, if they are shot (which they probably are not). Any ancient capacitors would be more of a worry, depending on what construction they employ.

    Selenium rectifiers certainly show its age, at lease they aren't mercury tube rectifiers, although those do emit a nice glow. You might like this series ... .. nothing much to do with clocks or watches, but lots of stuff about contemporary vintage equipment.

    The important question is.. does it go. The next most important question is.. what is the piece of paper wedged between the contacts of the middle switch in the mechanism shot doing, does it allow you an extra 15 minutes in your bed each morning
  16. Something more like this perhaps? I'll keep an eye out for it on ebay for you shall I (calibre 89 18ct IWC watch from 1946)

    ETA GMT movement?

    .. on the other hand, there is the ETA 2893-2 automatic GMT for example... https://www.ebay.co.uk/itm/Authentic-ETA-2893-2-automatic-GMT-watch-movement-Victorinox/132919302254?hash=item1ef29b986e:g:KOMAAOSwuJRcG5Kj:rk:55:pf:0

    I don't know the answer to your question specifically, but I was recently reading about Chinese ETA clones, and your question had me looking back through my history.. https://www.borealiswatch.com/hangzhou-6460-gmt-automatic-movement-based-in-eta-2836-2-gmt-movement/ That might be of interest.

    Omega cal.t17 help

    Broken/worn pivot or jewel on the balance fork? Broken or worn pivot or missing/poor spring on balance, or damaged balance jewels? Is it worse in some orientations than others? I had something similar on a watch recently, and the pivot on the top of the balance staff was worn to a small nub. The moment you moved the watch, it was all over the place, but if you kept it still, dial down, it ran perfectly. I replaced the balance, simply because I already had a donor movement, and it ran perfectly.

    It reminds me of the sort of thing you would have seen in some of the big factories I visited over the years. I'd place it somewhere between the late 50s and the late seventies. These things were the bane of the tardy worker, as they were linked to the clocking in system. If you clocked in 5 mins late you were docked 1/2hrs pay, up to 15 mins and you lost an hour, and anything more and you were hauled up before the manager.
