That is an Accutron tuning fork watch. I wouldn't advise a newbie to attempt this. The repair would require a microscope, an Accutron tester, a multimeter, a variable power supply and specialized tools.

There are a lot of articles and videos on the web explaining the inner workings of an Accutron. Absorb everything you can and then decide if you are ready for it.

If you are looking for a battery watch to dabble with, perhaps a modern quartz watch would be a good starting point. Or an electromechanical watch like a Timex Electric, Hamilton Electric, Dynatron, Cosmotron.

Sure is beautiful though, isn't it? I've been researching and accumulating tools, power supplies, and meters to service 218 movements for quite some time now, and it's still very intimidating.

If you do try to tackle it, let us know! I've got a half dozen movements at home in the queue.

accumulating

the other thing you want to accumulate if you working on tuning fork watches are the parts. In particular the index wheel's. They have a habit of not lasting forever they have held up quite well but the super tiny teeth just don't last forever so really want to have key spare parts just in case.

Has anyone, outside of the factory, succeeded in making a new index wheel?

before I get into index wheel's let's see what were talking about that has index wheel's. The first website talks about the tuning fork watches. On the second page is the gallery page see how many tuning fork watches you see? I'm not seeing at something in particular so I think at least one watch or actually several are missing. The link scroll down until you get the tuning fork watches he mentions the one that's missing but doesn't have any pictures. The second link is interesting because basically it's the contents of the book which has been referenced in the first link somewhere in the website they talk about this book if you're into electric watches the book is nicer than the website though and is still missing at least one picture

okay found the missing watch which brings up a question who made their index wheel? We have the Russians on the fourth flank with their clone of the 214 and their stylish different color. We of the Swiss working out how it to break Bulova's patent sort of with their index wheel which is a different number of teeth in fact in Bulova's watches. Then we have citizen that has a different version of the 219 and I guess because citizen of Bulova working together they probably made the watches together probably the same machinery

then there was the re-issue a tuning fork watch from Bulova no idea whether they recycled or had a backlog of index wheel somewhere although I don't think so.

So as far as I know other than the minor mysteries I brought up only Bulova made index wheel's with a certain mystery as to how they were actually made.

    • It's from Rolex spare parts catalogue published around 1940-1950. They are quite expensive and hard to find one. For future reference you can use https://thewatchmakersapp.com - at the moment that app has the most reliable and complete Rolex movements calibers listing available (around 100 and adding more) including all vintage movements from this catalogue (with scanned technical sheets linked), some of that info is not available anywhere else.
    • I believe @nickelsilver has a setup like that.
    • I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.
    • Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.
    • One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
