I've had this wach now as my daily wear/beater for over a year and I can't say enough good thinks about the bang for the buck. Well made, solid. Love the plastic display back, this is a great feature on any automatic. The diver style bezel is one way and requires enough effort to move that it won't happen accidentally. The watch is very durable. I'm not kind to timepieces and this one has taken it's share of knocks without issue. It is also water resistant in normal use, I shower with it on and have had it at the beach and in the rain. It lacks some of the true diver construction but I'd say that's not really it's intended purpose.

I suspect a lot of people looking at this watch will wonder about size. It's listed some places as 41mm, some 43mm and some as large as 45mm. I measured mine and it is 43mm not including the crown. (Edit, I remeasured after the comment below. It's really 41mm case diameter, 40mm bezel diameter.) I've also included several wrist shots for reference on the product page. I have a  17.5cm wrist or 6.8 inches.

So downsides? The large "Seiko 5 Sports" logo is out of place on the dial. A nice clean "seiko" would make this more of a classic look. The bezel paint has picked up quite a few small chips/scratches. Well, what do you want, it's not an expensive ceramic bezel like a new rolex/omega. Other than that I really have no complaints. Again, for the money it's an excellent watch.
