Thanks for all the replies. Buy sporty I mean something that goes well with jeans and can take a beating so I'm a fan of rubber bands and ceramic boxes.

I'm still leaning very much towards the Oktopus but likely will hold off until I travel before buying so I can see and feel the piece. While LW seems to have a wicked online buying policy I'm just more partial to hitting up a shop.

Also on (and off the radar)

PAM104 - Still have my eye on this although having to replace the band and the steel box are a drawback. That and it kind of feels like a watch past its prime. Like the price point though.
Bell & Ross - Off the radar, although cheaper it looks like a rich man's Nixon.
J12 Marine - Can't get over the Miata feeling of a J12 and seems overpriced for what you get.
Hublot BB Black Magic - Love but more than I want to drop.
Omega Seamaster Plantet Ocean - Probably 3rd on the radar behind the Okto and PAM, just feels a bit common.

Still open to suggestions of course.
