From outside look, they look the same except that the 1120 has an index(typical ETA design) on it's balance-cock and the 2500 doesn't... The 2500 also has regulating stud-screws on it's balance and the 1120 doesn't. All in all, the 2500 is a very advanced 1120 and also need less oil/service due to it's co-axial escapment: I would go for the 2500 in front of a 1120 without any doubt. But if you prefer the SM look: It's out in co-axial version now PS: I got both mvt at home and can give you pics if you need...
