I just got my 511 Subaqua Chronograph and I am impressed.  The watch is definately not for everyone, but it is eyecatching.  It is a big watch even for my size but at the same time looks great.  I am in the military and wear a cheapo but dependable Casio as my work watch and wanted to upgrade my going out watches and this was a great pick.  This dwarfs my Casio and my Relic watch by both width and size, but looks so much better.  I was a little worried with the plastic band but the watch face and look it works.  The directions and crown face to adjust the watch tim and date is fairly easy....if you struggle just follow the directions and play with it.  The only problem I may have is making this my only Invicta watch because the Venom may be my next buy.  In all a very good look looking and practical watch.
