candide2424 Posted September 13, 2018 Report Share Posted September 13, 2018 Helloy guys, I bought off ebay a watch (rather cheap) with a very nice no date ETA 2821-2. I had never heard of this movement before. In my opinion it might be a nice replacement for a 2846 as there is no modifications to make in order to remove the date. However I have fnot found much info regarding its measurements (stem height). Thus, it might not be a direct swap: Do you have any info? Thanks Link to comment Share on other sites More sharing options...
automatico Posted September 13, 2018 Report Share Posted September 13, 2018 The 2821 is an older movement and some vintage Rado watches had them going by what I have seen for sale. I have never owned a 2821 but my guess is they are basically the same as an Eta 2824. I looked around on the 'net and could not find 2821 measurements. Most are 17 jewel but a higher jewel count autowind assembly will probably fit. "In my opinion it might be a nice replacement for a 2846." A 2846 (day and date) is a little bit thicker than a 2824 (date only) and the stem will not be centered in the case tube when used in a case made for a 2824. I ran into this on my JMB '1016' project. So...a 2821 (assuming it is the same size as a 2824) may not mount correctly in a case made for a 2846. Link to comment Share on other sites More sharing options...
alligoat Posted September 13, 2018 Report Share Posted September 13, 2018 I always go to Ranfft to check out movements, but the 2821 isn't listed there! You'd have to assume it 11.5 "' and based on the 2801 or the 2824. I found a 2819 http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&ETA_2819 but it beats at 36000. If the 2821 is an automatic, no date, I'd figure it's thinner than the 2824, but probably not by much. Link to comment Share on other sites More sharing options...
candide2424 Posted September 14, 2018 Author Report Share Posted September 14, 2018 I go to Ranfft too, but this time I did not manage to find any info related to ETA 2821-1 Link to comment Share on other sites More sharing options...
capice Posted September 14, 2018 Report Share Posted September 14, 2018 Size of the 2821 is 11 1/2''' 1.50 x 0,90, same size as 2824-2 Link to comment Share on other sites More sharing options...

jmb Posted September 14, 2018 Report Share Posted September 14, 2018 Looking at the ETA data sheet (off Cousins site) it shares quite a few characteristics with the 2824. Link to comment Share on other sites More sharing options...
