I've scoured the usual sources, including the ETA Customer Service site, but I can't seem to find a cross reference for the dial feet locations on an ETA 2783 compared with the 2824 or 2836 movements.  Many aftermarket dials are advertised as fitting these latter movements and if I can determine whether the location and diameter of their dial holes match my 2783, then I'm sure to succeed with an aftermarket dial.

The dial feet holes on the 2783 are at (eye-balling) 11 minutes and 41 minutes, and center-to-center diameter of 24.0mm.

Any suggestions for a data source?  Anyone have a 2824 or 2836 sitting on their bench and their calipers close at hand and bounce me a reply with a measurement as above?

Thanks as always.

I found the answer to my question - the Ofrei site offers dials to fit 2801, 2824, 2836, etc and their site cross referenced the 805.111/4 series as fitting the same dials, so I looked up the 805.112 on the ETA SA Customer Portal ( http://www.eta.ch/index.php?id=7&L=2 )  and there is indeed a spec drawing:    Doesn't match the 2873 at all, regrettably.

Now, on to Plan B - which I'm sure I'll determine soon. 

BTW, anyone done a dial swap on an ETA 2783?  Dial dots the answer?  Anyone ever successfully add/move dial feet?  Any advice (other than 'stick to bicycle repair') welcome.

Thanks

Hi and welcome!

I wouldn't know about the position of the dial feet you are looking for but -- as far as I know -- only people with the right equipment (soldering machine, etc) have been completely successful in achieving this dial feet replacement/repositioning. When I have this problem, I use stick on dial feet available from many vendors and/or double sided tape designed for the purpose (also from many vendors. I try to avoid this solution as much as I can though.

I hope this helps,

Cheers,

Bob

I should have been quicker on the draw....

I have examples of both 2783 and 2836 in my parts bin so I just tried swapping them out and no joy.

So I then went on to measure the dial feet location as best as I could and the results are as attached.

Basically both movements have dial feet that are 0.72mm diameter, diametrically opposite each other on 24.8mm centres, but displaced by 5 degrees between the two movements, so they will fit but nothing will line up.

I Conquer with Bob,

I have use thin two sided tape countless times setting a dial with broken legs! it works as long as you are careful not to put any tape over a date wheel where it might get stuck and interfere with the free rotation of the date wheel.

but like I said used it with date wheels and so forth just need to pay attention.

last month saw one of the watches I did 3 years ago and it was still going strong[emoji1303]

    • 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/
