G-ShockG-Shock GW6900-1 Men's Tough Solar Black Resin Sport Watch

I am very happy with this watch. This is my first Casio G-Shock and so far, I love it. I think the size and shape are just right and I like the functionality. I was a little worried that it might be a little big and bulky on my wrist but I think it fits just right. I have an average size wrist and the watch doesn't look abnormally big on me.I really like the solar function. I wore Timex Ironman watches for years but changing the batteries was such a hassle due to the difficulty in getting the back off with the wrist band in the way. And I had to replace a couple of watches when I didn't get the back sealed properly and water got inside. I'm hoping that with this solar powered one, battery replacement is a thing of the past! It really doesn't take much effort to keep the battery fully charged. When I got the watch in the mail the battery level was at the third level (of four), or the level just below full charge. Initially it took a little bit to get the charge up to full and it went back and forth from full charge to down a level a few times over the first few days. I'm assuming the watch had been sitting in a warehouse out of the light for who knows how long so it probably needed some extended light exposure to fully charge. After a few days I was careful the expose the watch to direct sunlight for longer periods and that brought the charge up to full and it stayed there. Since then I haven't made any special effort to expose the watch face to light (sun or electric), just the exposure it gets through normal everyday use, and it has stayed fully charged.I've been really happy with the atomic timekeeping as well. The instructions go to great lengths to explain how you need to position the watch a certain way on a window sill at night so that the watch can receive the time keeping radio signals. It sounded like it was going to be a real pain since I prefer to sleep with my watch on. So far my watch hasn't missed the signal once even though it stays on my wrist in bed at night. I imagine that results might vary depending on where in the country (or world) you live and what the surrounding terrain is like. I live in the northeast US and in pretty hilly terrain but so far, no problems with reception.Other than those specifics, I like the overall look and function of the watch. I was concerned the numbers might be a little small but so far that has been fine. Figuring out the controls was not difficult. I did read the instruction manual to find out about some of the specific functions but overall I just played with the buttons a little bit and most of it is pretty intuitive.I've only had the watch for a few weeks so I can't speak toward it's long term durability but it definitely seems very well constructed and I look forward to many years of service. It looks like the band is relatively easy to replace should the need arise. Overall I think it is a great watch. If you are looking for something that is functional and durable, I highly recommend the G-Shock GW6900-1!

After having journeyed into the realm of many expensive watch brands, I came back to Casio for a watch that I could wear and beat up. Prior to this I had a Timex Ironman Shock Solar but it ended up not working right. After sending it back for repair the first time it came back and then broke again, I gave up on Timex and sold it.After using the Casio for a month or two now, I can honestly say that I like this watch better than anything else I own. I wear this more than my Suunto, Rolex, Tag or anything else because of it's durability and ease of use. The watch is also accurate. It syncs up to the Naval clock every evening and I never have to set it.With the press of a button I can also see the time in Asia and with another button press I can see Europe. I do business on three continents so this feature helps me coordinate calls with my colleagues over seas.The watch is light and water resistant to 200 meters, so you could scuba dive with it if you wanted. It has a stainless steel back that is stamped Made in Thailand, along with some other information about the watch (water resistance, model, etc).My main problem with most G-Shocks is that they look like you are going to invade a country as the size is extremely large (think a rubberized Panerai). I have smaller wrists at 7 inches and the watch looks great as it is about 1 and 7/8 inch at it's widest point.The backlight is super effective at lighting up all the registers and letting you glance at the time. It can be accessed by pressing the big black "G" button on the front of the watch.With the watch being solar I am not anticipating any problems with battery life. It has remained on full since I had it.I run and lift with it on about everyday now and it has been to the pool a number of times without any issue. It still looks new.Buttons are easy for my larger fingers to press and setting the time is a breeze versus my chronometer watches (my Aquaracer is next to impossible for me to wind as the crown hurts my fingers).There are multiple functions to the watch including world time, multiple alarms, countdown timer, and stopwatch. The display shows the day, month, date, and time.The band looks like it could easily be changed as there are four screws that hold it on, so I imagine if you wanted to put a NATO strap or something else on, it wouldn't be a problem.To summarize, this is the best watch I now own and I would say it is my favorite. I have even thought about selling my others, as I am just not wearing them anymore. I am not sure I would pull this off with a suit though. Although, it really doesn't matter what others think, I believe you can pull off anything if you have the confidence to back it up.
