Hi there,
I would go for the heritage but I'm biased as I have got a YG heritage as a daily wearer for about two years now.
Fantastic watch that goes good with anything you wear up or down. I wear a suit to the office every day but the watch looks just as nice on jeans over the week end.
What I like about the heritage is that it has all the classic Breguet DNA (blue open worked hands, guilloche dial) yet it has some kind of casual elegance to itdue to the tonneau shaped case (a bit like the enfant terrible of the Breguet family).
Generously proportioned it's a very legible and quite masculine watch without being bulky. It's a watch you don't see every day so guaranteed to raise questions with from other watch enthousiasts.
On the downside maybe, the case is a bit of a scratch magnet but then again the watch is too beautiful to keep in a drawer.
Happy hunting and please post a pic of the outcome.
Best regards,
Jan
