I love this this watch, i have it now for a few days, and it's simplicity, solid construction, and it's look all make you love it. but with the advantages comes the disadvantages:
br /1)it's heavier then the newer models
br /2)it's big
br /3)the screen is half taken by some half-functional graphics
br /4)you can't set the alarm with the back light on
br /5)it only has 1 alarm clock (other models have up to 5)
br /6)the battery only lasts for 2 years (by manufacture) - other can last up to 5 years. (note you cant change the battery on yourself)
br /7)it lacks the auto light-on option (light turns on every time you pick you arm to look at the time)
br /8)the buttons are metal, and not covered by plastic or rubber like in other models, i can see how dirt can get stuck there.

br /Casio made a long way in development or their watches, and i see no reason to skimp on the 15$ or more separating between this model to others, more updated models. with that said, there is nothing really wrong with this model, it's reliable (by others confessions), it's glass is very strong, and the overall construction is extremely solid - almost to the way it will make you smash it in hard objects, just to see if it's still works.
br /in conclusion. i had i chance to replace this one with other models, but i didn't, i preferred to save the few dollars, and stick with this one, mainly because i am looking to serve in the military with this watch, and most of the extra option (Auto-Light, 5 alarms,different time zones) are just not useful for military service.
br /but for any other use, i recommend looking at different Casio models, do it fast, before this watch reliability will make you fall in love with it, and develop guilt for discarding an old friend.

This is my husband's second watch G-shock watch. His first lasted for 6 years before the band broke. He never had to replace the battery or anything! This one seems to be just as durable.

I have owned G-Shock watches for years. I am on my fourth one, and they have all lasted years. I wear it 24 hours a day, and never take it off. These watches are tough, I would not own anything else.

Awesome watch! I used to have one about 10 yrs ago and lost it and finally bought another one. Tough, durable, and great for the price! I wore it snorkeling in Hawaii and have bumped it against many walls and it still looks new.

As usual, very please with the G-Shock. They are the only watches that can survive for more than a few weeks when worn by my Marine Engineer husband!

I purchased this watch for ~$70 almost 4 years ago to add to my G-Shock collection and have been wearing (and abusing) it ever since. The watch is extremely robust and has never let me down. These G-Shocks are something of a true gem in the watch market. And hey, in case you need another reason to buy this tough boy, the DW6900 is part of a select group of watches (along with it's brother - the DW5900) that are flight qualified for NASA space missions! How cool is that?

In a few years I went through at least 10 watches, and this one is one of the toughest Ive had. I have a Luminox that I bought for 3X the price but I still keep on coming back to this one.

br /It has taken more punishment then I thought possible and come out with only small scratch.

I have had two of these and will buy a third soon. Why? Well, I have a knack for losing them. I had my first for close to 7 years (on the original battery) before I lost it. Bought a second one and that one dissapeared within months. You could say I'm not meant to have this watch but it's so good (and cheap enough @ amazon) that I will keep buying it. It is big and very sporty though, so I use it only for rugged outdoor activities, very informal wear, and sports.

Well first off the people who sent the watch sent it quick, real quick about 4 days. Second is the product, a G-Shock watch is the best you can buy. Forget all those nice gold, silver, titanium watches and pick up a Casio. For the past 9 years I had the same watch, a g-shock. I put it through way above average abuse, Skateboarding (my Job and life), Lanscaping, ocean and pool swims, and hot weather to cold weather. Casio is japanese work at its finest. So if you like the price buy it. theres no way you can go wrong with G-Shock.

I've taken this watch hiking, camping, and night snorkeling/spearfishing. Nothing fancy, just a solid, rugged, dependable time piece. Finally, after many many years of use, the battery is finally going south and the LCD fades dramatically whenever I use the backlight. But the cost vs use ratio has been unbeatable compared to my other watches.

I purchased this watch as a gift for a nephew graduating boot camp at the Paris Island Marine base basic boot camp facility. I weas told this is the watch that the marines wear, and I wanted him to have it. He appears to be very happy with the watch.

I am very pleased with the service provided. The express shipping allowed me to receive my order in time for Christmas and he was very happy with it.

I've owned one of this beauties for several years (I lost the count) and simply they are undestructible!! This is the best watch of its kind, and also unexpensive for what it is. I recommend it 100% if what you want is a simple yet powerful sports watch.
