Reviews 5 stars rating

Casio G-Shock Gravitymaster Men's Black Resin Bracelet Watch is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great Value G shock at this price! Not the biggest, or chunkiest of g-shocks, only slightly smaller in diameter than the 'Rangeman'. Very clear analogue (hands) display and probably the clearest digital display I have ever seen on a g-shock. G shock connect Android mobile app much better than earlier Edifice app. Reliable Bluetooth connection and much more functionality within the app. Updates time automatically 4 times a day without having to touch the watch or your mobile. (As long as Bluetooth is enabled on your mobile, the g-shock app is installed on your mobile and the phone and your watch are close to eachother) Not quite as convenient or reliable as the radio controlled multi- band 6 g-shock I have, but not bad at all. Or you can manually update the time with the press of one button on the watch, as long as the same criteria as above are met. Just a quick start manual is supplied, though the full manual is easy to find on the internet. (Search 'Casio module 5536') Images do not do it justice. Well worth the money at less than half price. By no means a 'top of the range' premium g-shock, but very nice for everyday use. Very comfortable to wear, though the strap may be a little long for the thinner wrist. (a common complaint of reviewers) Fast dispatch from H. Samuel too.
