Love this watch
Really amazing watch. So far I am very happy with the watch. It looks great and feels great when wearing. Setting up the time was a bit more difficult but reading the instructions for a second time helped. Feels really great on the wrist. Not too tight not too loose. It’s fairly easy to read from the negative display when outside, inside slightly less visible but still visible. Weight is really good! Not feeling cheap like a replica and not too heavy in the wrist, just perfect. Also, the experience of some users reporting that the watch gets dirty over time i can say for me is not the case. Mine is still as white as on the day I got it.

Cool as flip and works well..
I have rated this item 5* because it is so well made, of quality construction and looks the business when I wear it. I basically wanted a watch that could take a knock, wouldn't fall to bits the second I take it in the pool, and looks the schizzle when I'm mincing about in Ibiza in my shorts and tees.. The bracelet itself is quite chunky which I like and the fact it's white is really cool. The instructions are pretty easy to follow to set up World Time (dual time zones) and hitting A&B at the same time to swap between time zones is a brilliant little trick as well! Overall, if you want something a little different but that looks great on your wrist whether with shorts and a tee or when you're dressed to impress, look no further!

A smart looking watch- great value and highly recommended
-There is a clear display of the time (obvious from the picture) -Date, month and day are clearly displayed on the face of the watch. -There are some nice touches that you programme to your personal preference like 'auto light'. -It looks good. -It has an alarm and hourly signal alert (which can be turned off) -The things that are 'on' (like alarms) are shown by an indicator on the top left of the dial. If you follow the instructions it is fairly easy to programme. On reflection it programmes in much the same way as the casio watch that I wore to school in the late 1970s. There is nothing pretentious about this watch and you are far less likely to get mugged on the underground with this type of watch than certain other types of watch with loads of gold and jewellery on them. Why look for trouble?

New to G-Shock and now want more....
Bought this on Saturday late afternoon and was delivered Monday for my husband i cant complain about how quick the delivery was i thought it was going to come on Tuesday so very happy. The watch it self is amazing looking and very rugged feel and feels like it would last came in a nice rugged container with warranty and a BIG instruction book for night reading!! only down side to the watch is fiddly to use and work how to use it being a man had a quick look in the instructions but far to much to read for a watch other than that im very happy and now looking to add to the collection with the black and blue watch shown on here.......

Fantastic Watch
Brought as a weekend/holiday watch, I couldn't be happier. Haven't been able to figure out most of the settings, but love how it moves the hands automatically when you change the time zone settings. Is a very large watch, so if you have a puny wrist it may not be for you. Otherwise it is a great big white watch, that looks fantastic, and takes a hell of a beating, and then still looks fantastic.

Solid Watch / Easy to Use / Looks Great
I bought the White version of this watch and it is very eye catching. I also wear a medical wristband so I find the watch does draw attention to it (because they are both white). For the size of it, it is really light on my wrist. There's not much else to say, oh it tells the time really good :)

Affidabile, resistente, elegante, versatile, questi sono alcuni degli aggettivi possono descrivere questo orologio nella sua complessità. Sono molto felice di aver acquistato questo oggetto, mai riscontrati problemi, l'unico mio consiglio e' quello di acquistare insieme all'orologio, delle protezioni per lo schermo cossi che non si graffi e rimanga impeccabile.

Diese Uhr ist wirklich wasserdicht, auch zum tauchen geeignet, allerdings nicht fuer Tiefseetauchen, sondern vielmehr fuer Hobbytauchen ohne Taucher-Equipment. Die Uhr verfuegt ueber eine eine zweite Zeitzonen-Anzeige, die man sehr leicht umstellen kann. Nach meiner manuellen Zaehlung verfuegt diese Uhr ueber 49 verschiedene Zeitzonen. Sie ist sehr hart im Nehmen. Das heisst, sie kann kann auch ruhig mal zu Boden fallen (aus 2 Meter Hoehe) oder auch Dauervibration am Handgelenk (gearbeitet mit Presslufthammer) . Das coolste find ich die Uhrzeit-Einstellung. Die wird zuerst mit der Digital-Uhrzeit-Anzeige eingestellt. Sobald Sie die Zeit und das Datum eingestellt haben und dies mit der SET-Taste bestaetigt haben, drehen sich der Minuten- und Stundenzeiger auf die Zeiteinstellung, die Sie eingegeben haben. Diese Uhr ist waermstens zu empfehlen, da sie auch einen Timer, sowie eine Stoppuhr und ein eingebautes Licht beinhaltet, und zudem sehr robust ist, fuer Kenner und Liebhaber von CASIO G-SHOCK - Uhren.
