This G Shock MTG is a durable solar atomic watch built for everyday wear, with 200 meter water resistance, shock resistance, and a large digital display that is easy to read at a glance. The stainless steel band uses spring bars, which makes resizing easier, and the atomic sync keeps the time accurate without battery changes or manual setting. It also offers world time, a countdown timer, a stopwatch, and five alarms. The main knocks are its bulky, top heavy feel and a display style that looks dated next to newer G Shock models. A rugged workhorse if you want toughness over refinement.

  • The watch can sync to the atomic clock feed via WWVB and additional global sources for frequent time updates.

  • The stainless steel band uses spring bars, which can make resizing easier at home than some other metal-band watches.

  • The watch can keep running for years without battery replacement or manual time setting while syncing nightly.

  • The watch can keep working long-term, and a replacement band can be sourced on eBay after the original band breaks.

  • The watch can feel big and top-heavy, which may lead to snagging on shirt sleeves during wear.

  • The display can show a hovering or shadowing effect, which may reduce legibility compared with the GW-M5610U.

  • The watch may not be fully metal, since it can be mostly plastic with only some band links made of metal.

  • The watch's battery replacement can be difficult, since the CTL1616 cell reportedly died after about two years and replacement was hard to find.

Seriously... Pulled the trigger a few weeks ago when it was on sale for the same price. Very nice on my wrist, a solid 9 here....a nice bonus to sync my automatic watches to it as well.

https://www.amazon.com/Casio-G-Sh...172&sr=8-4 I have had this one for the last 10 years and it is still going strong. Loved it in general but also because it syncs to the atomic clock every night no one can ever say your late when their watch is off. Just when anyone argues with you your watch is wrong you just get the automatic win! Never replaced the battery, never set the time just put it on an take it off and it just keep doing watch stuff! Love my Casio can't think of a reason to own any other watch!

Would you take your smart watch scuba diving, or even surfing?
Yeah, why not?

I bought one of these many years ago. Then the band broke and it sat in a cupboard. Then my son needed a watch to wear surfing. It still worked flawlessly and I found a new band on eBay. Is a tough watch
