mmm...not 100% certain about this one's retention.
in general, most precious metal pieces tend to devalue at the point of purchase.
other than gold nautiluses, i've very rarely seen PM models from any brand increase in value unless they are absolutely collectable...like the original gold apollo speedy.
the fact that the re-issue is...well, a re-issue...i'm not fully certain that it will retain its value.
look at the current two speedy tuesdays....they're not really jumping up in price. and that silver snoopy is a red herring, imo.
historically speaking, i don't believe there are a whole lot of omegas out there that are highly coveted collectables, other than a few original pre-moon speedys. and those are steel.
my advice to you is buy with ur heart, not your wallet.
if u can afford the retail price on this piece, then enjoy it.
beyond that, ur guess is as good as mine
