Good watch, few problems
Pros: the watch is durable, functional,customizeable, has a relatively simple manual, has a neat auto-light function (not extremely useful, but cool nevertheless), and is very stylish. Cons: the ones you've heard before: weak backlight(can be fixed by holding your finger over top half of watch while backlight is on). I don't know if others have experienced this, but my watch came with the speedometer hand off by a hair (fixable by navigating to time/date mode and holding "forward", then adjusting the hands to their 12 o'clock positions with "forward", "reverse" and "mode" buttons. Another minor con is the fact that the speedometer is not, in fact a speedometer, but a calculator of distance/time based on previously entered data. If I had done a little more research, this would've been clear to me. Overall, I would definitely recommend this watch to a friend (and have done so before), I haven't spent a day without it on.

I really like it.
I have had three of the same Timex Ironman watches over the years. The big problem that I had was that first the loop for excess band length would break--- that was easily remedied by using an o-ring to replace it. Then within a couple of months of that the band would always break. I have tried to find a replacement band without luck. Unfortunately the band has a non straight end that keys into the watch body which more or less prevents using an aftermarket band of any type. Plus I wanted something different. So this time around (no pun intended!) I decided on finding a watch that I can get a band for and over the holidays I saw a G-Shock at a local store and it stuck in my mind. This is for a everyday watch that I wear and the functions that really matter are time and date--- the rest is just the proverbial "added bonus". So I could not decide between this one and the one that is all black--- so with free returns I bought both as well as one other to try out. The other was fine, but simply too small in diameter. Maybe when I was in my teens it would work, but as an adult--- just didn't look large enough. So I sat both this one with the red and the all black side by side. I kept using the functions and it really came down to reality--- I need to be able to see the face as easily as possible. So the all black that has all black lettering and the black inverted display on the digital part--- I know it will bother me over time and I will learn not to like it. So I decided to keep this one. I do like the red accents and the buttons are clearly labeled plus the display may not be as sexy as the other in black, but it is easier to see all the time. And as far as the red hour hand being hard to see--- for me it is not a problem. I have made a point of looking at it at different parts of the day--- it is always normal to read. Yes the hands do get in the way of the digital readout at specific times of the day, but for me it is not a big deal. Overall styling is great for a resin type watch and it feels good on my wrist. As far as size, it is almost exactly 2" from button to button on the diagonal and is about 1/2" thick. I thought it may have been too big, but it is just right. As far as price--- compared to some similar watches in the same range--- I will stick with the G-Shock. I have also ordered a spare band so that when it does eventually break--- I will have a spare ready to go. For setup I never even read the book. Took less than 1-minute to do and the longest part was scrolling through the time zones and then remembering if we are on DST or not. As far as the backlight it is amber and factory set for 1-second. After reading another review on the all black version--- in the adjustment menu there is the option to change it to 3-second which I did. Again, easy to do and happy with it!

Fantastic value...
After years of cheap knock offs and even a few Armitrons, all in the $20 to $35 range, I broke down and spent $85 on this genuine G-Shock... and I wish I had sooner. Pros: Very rugged Stylish Easy to read date and day Constantly displayed seconds timer Large, easy to use buttons Adjustments are easy and intuitive. No instructions necessary unlike my Citizen Blue Angels Eco-Drive that you need an engineering degree just to be able to follow the instructions Bright LED light Excellent, easy to adjust band Cons: Hour hand is a bit hard to see LED is an "across the face" light rather than a backlight and it only stays on for 1.5 seconds. The plastic case has "protection knobs" that partially cover the crystal, thus providing a place for dirt to collect The "crystal" seems to scratch a bit easier than I thought it would (or should) and I highly recommend a watch crystal protector A bit expensive when compared with other "rugged" watches but well worth the investment in the long run.

Exactly what I needed
I play ultimate with a group at lunch and we never knew what time we needed to leave because everyone would take their watches off. I bought this from Amazon for a great price. It looks nice. And after playing Ultimate with this watch on for probably 100 hours now of sweating, running, and bumping, I do not have one scratch on the watch. I did cause some blemishes on the band by spraying it with mosquito repellent, so be careful with that. I do agree with other reviewers that the red hour hand can be a little hard to read especially at night, but I haven't had a problem telling time out on the field. For me, it does what I need. I have peace of mind that my timepiece is practically indestructible and looks great to boot.
