"Heritage", on the one hand some brands do produce "Heritage" which have a very close relation both aesthetically and from a feeling point of view. On the other hand some brands produce "Heritage" watches with very little or no resemblance with their original ancestors. This Longines, in my opinion fits in the second category, besides the shape of the case, which is about the only part linking this "Heritage" to the original, everything else is different, 3 sub-dials, a date and an ETA movement!? I'd rather spend more, probably much more for an original Longine 1973 with a 30 CH movement or else I wouldn't go for a "Heritage" at all but just a "normal" Longines.
Just my opinion.
