It is a nice brand of watches, the style is good but can get really expensive sometimes... like every watch depends on the model, year, production, etc...
If you like it, go for it.
I'm a weird guy with the taste, I like classic watches like panerai or IWC and crazy fashion style like corum(bubble) as well(I'm 20 years lol, that should be it) so the U-Boat watches are just to big for me, but still
I would wear one haha
