ww12345 Posted March 17, 2015 Author Report Share Posted March 17, 2015 True. I guess I'll wait for the dial and then figure out which movement I'm going to use/drill. Link to comment Share on other sites More sharing options...
blue. Posted May 22, 2015 Report Share Posted May 22, 2015 A genuine 1570 dial would look like this, when the ETA is prepared to accept it: Notice the 57min dial foot. The foot has a few microns of clearance to the balance wheel. The 30min dial foot has a bit more clearance to the mainspring barrel. Testing the clearance with a sheet of paper passing freely through the gaps between mainspring barrel, the balance wheel and corresponding feet. All in all this has been done by hand with mini files, filing step by step, testing fit and centre to the movement. There is absolutely no margin for error. 1 Link to comment Share on other sites More sharing options...
ww12345 Posted May 22, 2015 Author Report Share Posted May 22, 2015 Yeah... That's what I'm worried about! Haha Know anybody can do the work? Link to comment Share on other sites More sharing options...
blue. Posted May 26, 2015 Report Share Posted May 26, 2015 Regarding the date wheel compatibility. In the above picture the franken is a no date, that is why I removed the date wheel and had no need to check if the 1570 dial feet would clear an ETA date wheel. Today as I am reviewing some pictures of the process "modding the main plate", I see that the gen ETA 2783 date wheel seems to have a quite small outer diameter. That is why I dare to claim that at least an ETA 2783 or 27xx family movement would work fine with the date complication and an 1570 dial installed. Here is a quick photo (bear in mind the 1570 feet holes had not been done at that stage when the picture was taken): Link to comment Share on other sites More sharing options...
mymanmatt Posted May 26, 2015 Report Share Posted May 26, 2015 For some dials the mainplate can be slotted, I've done it. The datejust cannot be done. I can do it for one foot, but the other foot prevents the set lever from operating correctly. As the set lever moves to the date set and time set position the foot next to it will not let it move up. I tried slotting the set lever, but it was to weak after it was cut. Link to comment Share on other sites More sharing options...
ww12345 Posted May 26, 2015 Author Report Share Posted May 26, 2015 So does that mean that the 1575 type dials wouldn't work either, Matt? Link to comment Share on other sites More sharing options...
pam007 Posted May 26, 2015 Report Share Posted May 26, 2015 Amazing work and interesting discussion. Didn't know any of this was possible prior to today. This is what RWG is all about Making things happen Link to comment Share on other sites More sharing options...
sneed12 Posted May 27, 2015 Report Share Posted May 27, 2015 (edited) Yeah, that's what I usually do. However, I read on here somewhere that someone had drilled holes in the ETA mainplate so they could use a gen dial, so I was hoping whoever that was would answer in this thread... For a modern 3135 dial and a 28xx ETA movement, it is not possible. One of the feet would go through the balance wheel. Other dial variants might have different dial feet positions.

ww12345 Posted May 28, 2015 Author Report Share Posted May 28, 2015 I was looking at a 1575 dial and a 27xx movement. Do you suppose that would work? Link to comment Share on other sites More sharing options...
