There you have it. Same price, both used, similar condition and with papers. I've been dying for both but will only be able to pick one.
From what I can tell:
Breitling: WR rating, bracelet, very liquid if I need to get rid of it. Minus: no chrono, arguably a "lesser" more common brand, ETA movement
Chopard: Chronograph, in-house movement (i think?), more subtle, a higher "tier" brand. Minus: not crazy about the rubber band, WR rating
Thoughts? I just can't decide.
