I can confirm that a 2836 will not fit with out the date overlay rubbing the dial causing the date not to properly advance. The eta 2824 will work on a non-stick dial. When I did my 15000 Date I had to use a 2824 because its thinner and then swapped out the pinion with this http://www.ebay.com/itm/HAND-HEIGHT-KIT-FOR-ETA-2824-2-H3-H4-H6-FOR-DO-IT-YOURSELF-CHANGE-/131732148773?var=&hash=item1eabd91225:m:mOt96At7UrNrstZYN9j2Dtg . If the pinion is not swapped the hands will hit the dial. I have heard if you use a lighter you can heat the crystal and remove the cyclops.
