In my opinion for 1500 builds, fitting a 2836-2 or 2846 (lowbeat equivalent of the 2836-2) is easier than to fit a 2824-2. This is because the 2836-2/2846 has a closer crown/stem/tube height to a gen 1500 / 15000 case, so it is less finicky to fit. On top of that, I recommend using the Helenarou movement ring (https://www.helenarou.com/eta-adapter-for-genuine-or-clone-rolex-5512-5515512551355141680.html) with the 1500 case. You might need to sand the inner and outer diameter of the movement ring to ensure a nicer/ snug fit.
Furthermore, here are the advantages of 2836-2/2846 movement:
- 2836-2/ 2846 movements have quick date flips at midnight like gen, unlike the 2824-2 where the date flips are gradual.
- 2836/ 2846 comes with taller H3 (or sometimes H4) cannon pinion and seconds wheel, which makes the hands clearing the dial easier
For your motivation, here is my superfranken 1500:
- Gen everything (including the 7835 bracelet and hands)
- Modified ETA 2846 lowbeat movement (to fit gen hands and to remove the quick-set date function, like gen 1570 movement)
- Cartel open 6/9 DWO
- Modified Helenarou movement ring
