There really aren't many choices for sub 40mm dive watches, otherwise I would've bought one in the $300 range. For the price I bought this as a beater watch for my beater, the Seiko SKX013.  I like that watch too much and I tend to get a lot of little scratches and dings on my watches, so I got this to see how much it gets messed up when I wear it around sand & rocks.  You really get more than you pay for with this watch.  The design looks good, the build, fit, and finish are surprisingly good.  For $54 I can't even really complain that the crown doesn't screw down and it seems likely that this "diver" watch would let water inside from a swim in the pool. The one thing I CAN complain about though is that the dial is purple under artificial light.  Why in the world would they make it like this.  A black dial w/blue bezel would make more sense than purple.  Even for a measly $54 I'm not sure if I'd want to keep it. What would people think of a purple watch on a guy.

Also note that this watch looks thinner and smaller that expected, and the 18mm tapered bracelet goes perfectly with it.  My Seiko SKX013, Sarb033, an Hamilton Khaki Field auto which are all 38mm all look bigger than this watch.  It's almost perfect for smaller wrists, but the lugs are a bit long.

Update:  Just received another variation of Invicta pro diver with the "open heart".  It is a much nicer shade of blue on both the dial and bezel.  It also costs the same now AND has a solid Seiko automatic movement. However it is 40mm, a bit chunky, and is at the upper limit in size for my 6.75 inch wrists.  For wrists smaller than that it might be too big.  I guess it's true, the watch industry really does hate smaller wrists!  I will be returning this one and keeping the 40mm.
