Thanks harry!
Hi harry, how are you? I have heard that you have already bought something truly precious. 
Indeed, the 5712 suffices, but the 3712 is very attractive, too tempting if you ask me. you see, i have been offered an unused 3712, and with the inherent rarity of this specific reference, i really want to take the plunge. BUT, i already have a 5712, a model that i truly admire. Difficult decision to make since both are essentially the same. I really do not know what to do.

3712 and 5712
Should anyone still buy a 3712/1A if he has already a 5712/1A? Your thoughts please. Thank you very much!
Now you ask the wrong guy!
In my books 3712 is the Original. It has the two-part-case like Gerald Genta designed his famed Nautilus while 5712 is having the conventional three-part-case. Furthermore, 3712 is a bit slimmer and there are also many other differences. I have listed som...
Thanks kari
Your admiration towards the 3712 is uncompromising and it is fascinating. Thank you for your insight!
You are the best advocate...
... of the 3712A there is out there. Well said about what matters, is that you know about all those small differences.
I think the 5712 should suffice ...
The complication is the same on the two models and the dial layout is almost similar, saved for a few details that are obvious only to WIS ;) With the 5712 you get the bonus of the exhibition case back which allows you to marvel on the inside movement. On...

It is still in the process :)
Well, if the 3712 is still on unused mode, then it already altered my original position. Could be worth a try then. Either way, there is no wrong answer. Thanks Kari for the correction.
A small correction...
3712 is equipped with exhibition case back. However, this watch is opened from the shoulders like the original 3700. Best, Kari
if you can afford, of course...
... if not, you might be tempted to swap 5712 for 3712 IF the deal is right. If its too harsh, i'd not go for it
I would look for something different
I own a 3712, wich I like a lot. It is different in many details and it is the "old" nautilus style. I remember that I paid the same amount then, like you have to pay for a 5711 today! I would go for another style or movement, if I already would call a 57...
