I am coming from a lifetime of using G Shock watches by Casio.  This Invicta watch is nice.  Would I spend $90 again on one?  No.  Probably not.  With all the bells that come with G Shock watches, I'd be more inclined to put my money there.  It tells time and has a stop watch.  Yes it is waterproof down to a good depth.  But here in Ohio, not much swimming in the ocean going on here in January.  What it doesn't have that i'm totally accustomed to is a back light and a calendar.  I look at my watch often and I really like to be reminded of the day and date, so that is what I miss most I guess.  While wearing this I do find myself using my iPhone a lot more to check the time and calendar too.  So, it is a good watch.  I like how it looks quite a bit.  Last thing I dislike would be the control buttons on the right side, simply because I wear it on my left wrist.  They are kind of large, and the center one really digs in pretty good.

Okay.  This watch is not worth the money!  Never keeps accurate time... that is until I set at the correct time.  I've had the watch into the jewelers for battery replacement, which is what I thought the problem was... He said batter has plenty of power, it's just poor design.  All in the hands, and their inability to go past/over one another.  They keep catching and don't have enough power to keep on going.  I can not and DO NOT recommend this watch to anyone.  Jeweler tip... He stays away from anything INVICTA makes.  Overall a poor brand to start with.  So, there you go.
