Excerpt: My only disappointment with this product is that on my current Timex Marathon, when I press down the Start/Stop key when in time mode, the month does not change to show the day of the week, a feature I used frequently on my previous two watches. I do not know whether it is a manufacturer’s change or a malfunction, but I still love my Timex Marathon and have learnt to not rely on it to tell me the day of the week anymore. My Timex Marathon Watch is durable and reliable.
Watch works great, Complainers don't understand mathematics...

Summary: I have been using this watch for about 2 months now. It tracks distance accurately (only about .1 mile difference between it and my Garmin Vista HCx at 10 miles). The part everyone seems to misunderstand is how it calculates average pace and speed. It updates real time pace data by averaging the last few points it tracked so if you changed speed (intervals) it will take a second to update.
