it's a great watch, if it doesn't reset on you.  This is my second Pro Trek watch, I love my first one but wanted an all black.  I read that the watches MAY reset in some of the reviews, I took my chances and mine will occasionally reset. Is it a hassle?, to a point yes.  I contacted Casio in regards to the watch and they said that it was a glitch for that model and that they would repair it for a "fee"?  It was still in warranty but unable to return to Amazon.  Feature wise this is a great watch for a good price. BUT, buyer beware regarding the resetting. I purchased mine in April of 2017 and within that time it has reset itself about 5-6 times
