It's really hard to compare the watches as they're different in every meaningful way! The Aquaman is no SUB but its a neat watch. The lume is excellent and the bezel rotates on 120 clicks. With 100m water resistance and a screwdown crown I've never had any issue diving with it. I actually really like the 24 hour time markers on the dial as an interesting touch. That led to a funny discussion last week with my brother, since I use 24-hour time on any device I own and all communications, telling me no one used that. When I said lots did he said why isn't it on a watch face then. Well, there it is! There's no Jennyfish on the caseback, just the Doxa 1889 logo. Same goes for the crown, which says DOXA on it.
The Aquaman is, imo, a well executed quartz watch and one I plan to keep in my collection just to have. It will probably be a good first Doxa for any future kids and its definitely a fairly uncommon watch over here.
