Huge congrats, for the watches and for the great taste !!!

I always preferred the earlier versions of the Carrera's - since about one year ago, then i got a 7753, then a 2447 2. Exe - and now, i must admit that i probably will prefer the later ones - as you wrote, the 60s models are more elegant, so pure, so 'all what you need, not more' ... the early 70s looks sportier, and probably more modern for me. All in all, it is difficult to decide, you did the best and bought both !!!! :)

Enjoy to the fullest!
