Graham Chronofighter Prodive Watch (Store-Display)

Yeah, not that bad.

Agreed. I have a huge VE Lunokhod diver that I couldn't break if I wanted to. Definitely what I wear when I'm working on the house, etc.

Size preference is quite subjective, and even I am not averse to a larger watch sometimes. I have a Citizen F150 that is so nicely executed that I excuse its 44mm case. The Ball World Timer is not something I might personally go for but I can see how shrinking a world timer would quickly make it illegible. The Speedy pro is actually on the large side at 42mm, but that case is something magical; it wears smaller and slimmer than its dimensions suggest, yet a Speedy never lacks wrist presence. The Seiko Monster is a special case. It's a bit of a paradox that I find it ugly, yet own one. Let me elaborate. The Monster is ugly in the same way a rhino is ugly. It's big and tough, and that's what you want in a diver. It almost looks incomplete without a few scars and scratches. Submariners and Seamasters are very nice, but that's exactly the problem. Unless you're disgustingly rich, you'd worry about doing anything that might damage them. The Monster's ugliness (and price) is more true to its function as a dive watch.
