Summary: As a past Corporate Computer Network Administrator, you should know the process for updating this Watch is do convoluted, I decided to not even attempt it. If it goes wrong, your Watch could be "toast.

Summary: Update: Not sure what's up w/ the Seller, but my Timex watch was to come with a heart rate monitor and AC adaptor--it didn't. Timex (not the Seller) provided responsive customer service to address this issue; therefore, I modified my rating. Further, unlike others, Timex did not request or encourage me to change my rating or comments--the choice was all mine based on my personal experience with Timex (not the Seller)--Timex (not the Seller) simply provided outstanding...
Summary: Before this watch, I had the Nike fuel band and nike gps watch. Let me just say that this watch is way better. It has all three functions of biking, swimming, and running. Also, it is waterproof (as long as you don't press the buttons underwater), which is a huge plus. Really easy to use.
Summary: I do like this watch. It is my first GPS watch and not bad at all. I have had it for a couple years now. It has held up well. It is nice having 4 screens at one time. The only thing I am not a big fan of is the size of the watch. It is a little on the big side. Also, I'm not sure if the battery would stay charged through a whole Ironman. I think the battery would definitely hold up on a half Ironman or less.
Summary: 1) it was very large and heavy. 2) Most important we could not get it to lock onto a satellite to work. the clock worked fine, but the other features did not. 3) It was difficult to find the instructions on how to charge it, and other important info on working it. (Thank goodness we thought to look up the info on the internet. All in All we were Very disappointed in in the product. and returned it.
Failed after 7 weeks, wasn't great when it did work

Summary: I purchased this watch 7 weeks ago and have used it 5-6 times/week ever since. The features were perfect for what I wanted it for and I only had two nitpicky complaints. 1) The GPS takes seemingly forever to find enough satellites; and 2) You have to have a computer of some sort to offload data. No phones, no tablets, nothing bluetooth, etc. Today, however, the unit has stopped working.
