The new bracelet are pretty the same in finishing in the last 30 years, the bracelets of the first serie (A serie) of ref. 5402 are a little bit less finished in the attachment to the case and in the single piece, perhaps the last deployante clap of ref. 15202 is not confortable in wearing due to the lenght of the clasp itself, but in the quality of the construction is a first class piece of work.
The new upcoming 15202 should solve this problem with a double deployante clasp.
Definitely, the quality of the bracelet is not the reason why i would prefer a 5402, whose cons are manyothers, like the design of the dial with its microtapisserie and long indexes and the small AP logo at 6 and the appeal of an historical reference.
