Summary: The watch works. I use it for running and the overall pace it gives is accurate. I have tested against the GPS on my phone and by running on a track. The biggest drawback is that when you change your running pace, the watch will take about a minute to reflect your new pace. I think it just takes your average pace over a minute or so, so if you want run long distances and add in a few intervals, you may not be able to immediately see when you speed up.
GPS is picked up almost instantly with the Garmin and the numbers are large and clear enough to be easily read.

Summary: If a person had no experience or comparison with other sport watches (GPS, stopwatch, etc), maybe this watch would be okay. But I doubt it. I have a Garmin that cost about $20 more and it is light years ahead of this watch. The primary problem is it won't pick up a GPS signal. When it does, it may have taken 20 or 30 minutes. You can't wait around to start your walk/run for the GPS signal to finally be picked up.
Summary: The Timex Marathon GPS Watch is a great addition to my running gear. This is the first GPS watch I have owned and it proves that good information changes performance for the better. In the Set mode, the watch has a time/date function that lets the user key in information by time zone. I use the Washington D.C. Daylight Savings zone. In Set, I selected Auto GPS so the watch uses satellite information from the GMT source for accurate time and date display.
Summary: GPS takes a LONG time to hook up. While this is an engineering issue - realistically it's hard to blame anyone for this - the battery lasts a very short amount of time, especially if you use the GPS. I often would find myself about to start a run, turn on the GPS (which could take several minutes - or not even hook up at all) and be promptly greeted by a flashing low battery signal.

Summary: Good watch, and the GPS initiates quickly for the most part. Maybe 5% of the time it really struggles to catch a signal, but that can typically be attributed to weather issues, or even my own impatience. The 4 instead of 5 relates to its insufficient user manual that comes with it. I can look up additional features, but it really should have been included.
Summary: I have been looking for a long time for a reasonable GPS watch to use when I am training for marathons. I have used several Garmin's in the past and when comparing this watch to the Garmin's I was pretty satisfied. Just like any GPS watch you will not get accurate data if you run under tree cover on a path or in the woods. However, the watch is accurate for distance, approximate pace and is easy to navigate and setup.
