I ordered this watch when my latest Timex Ironman watch started falling apart.  This one is not an Ironman watch but I figured it had most of the features I needed:  it's waterproof, has a highly visible face, has the calendar function displayed.  Unbeknownst to me, it also has a timer and a lap function which came as nice surprises.  The watch arrived two days after ordering.  I was pleased with the quick delivery time.  My  most pleasant surprise?  Unlike the Timex Ironman series of watches, of which I've had quite a few, setting this one is intuitive...you don't need to read the information booklet that came with it.  The use of the 4 buttons on the watch to switch between functions is also very easy to pick up, again, not requiring the instruction book.  All-in-all this was a very worthwhile purchase and I would do it again.
