ETA 2783 - Dial Feet


Recommended Posts

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]

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
