rated 5 out of 5 Well Worth It
by S. Shah from New Jersey, 2010-03-10


This watch is definitely awesome. I wear it everyday, and it hardly comes off my hand. In fact, it feels like its become part of me; I feel awkward when I'm not wearing it.



rated 3 out of 5 Decent
by Jason Hatstat , 2010-01-13


After going through a few other casio watches over the years always having moisture in the watch. I spent the extra cash on this model thinking it would solve my problems. Already had to send it back before even 1 year. We will see if they changed the seals or what they did. Disapointed. Thought I should get 10 years out of them. Love casio but wish they held up a little better.



rated 5 out of 5 A Great Watch - Works as Advertised
by Fire Walker from Rochester, NY, 2009-12-30


I've had this watch a couple weeks and I'm very satisfied. It's a sharp looking watch and sync's almost every night just sitting on my night stand. I live in Upstate New York just south of Lake Ontario. Each morning I check to see if the watch synced overnight and nine out of ten nights the sync has taken place. When I place the watch on a window sill the sync always takes place. The solar battery shows no sign of losing charge. The watch has a neat feature of shutting off the display each night to save battery usage. I highly recommend this watch.

by Richard Delgado from San Diego, CA, 2009-12-25


Very sharp Atomic Solar watch with auto light. Have two time sets such as PST and EST in different modes, great for traveling. Shows the month-day or day of the week, would be nice if they could show both. Watch is rust resistant. Completely digital readout. Very sharp looking and functional G-Shock.



rated 5 out of 5 One of the Best G-Shocks Available!
by Joseph Agasino from St. Louis, Missouri, 2009-12-11


I've had G-shocks since the early to mid nineties (not counting one as a kiddo). This model is a welcome addition to my collection. Size is manly without being too cumbersome, the titanium/resin construction keeps it light on the wrist (less than 1/2 the weight of a good stainless steel cased/bracelet watch), and all functions perform as they should.
Syncing is never an issue (midwest location), and even on those nights that it misses a sync, I know its still quartz accurate so will be within seconds per day. Manual syncs work well too! I can get an L3 signal when I attempt from next to a window mid-day in my home.
I really cannot think of any negatives....Casio G's are a sturdy, well made watch. The size might not be ideal for some situations (business shirts with long sleeves), but then again, I use it as a casual watch so its a non-issue. I also own a DW 6900 and it feels similar in comfort, though lighter than the DW. 5 stars, highly recommended.
