ETA 2824 vs. 2836 Caliber SHOOTOUT (Comparing All Aspects)

Both movements are very similar as the ETA 2836-2 is an advancement of the ETA 2824-2. The two movements have a similar diameter of 25.6mm. The main difference between these two movements is that 2836 holds a day-date calendar complication while 2824 houses only the date complication. That stands to be the major difference between these two
