... beside the hands and the brushing of the case, the main common point is how genta succeeded in doing a timeless design.
Main problem of the 5711 is that the 5712 looks so much nicer, makes the 5711 looks dry and boring.
If we want to be picky, the ears on the 5712 have no function unlike the 3712. That can be a weakness if you consider that to reach perfection, the function is the root from which the design can grow strong.
