Amazing product

Lovely watch, definitely value for money and nice clear face.
Every thing I would expect from a g shock with the added bonus of an analogue face, just what I wanted.

Great looking watch, but not the best for people with not so great eyesight.
It’s a beautiful looking watch, but as somebody with not so great eyesight, the dial, for me does not have enough contrast to it to be easily readable and the digital display is very small. Unfortunately, I had to return it because of this but there is no question it’s a lovely watch.

Looks ok but not up to standard .
In hindsight I would not have made this purchase. I cannot see the digital time hardly at all and the light is very low. If you look at the display in low light you can confuse the day hand with a different hand thus getting the time wrong.. It was a pain to set up and had to use you tube review for assistance. I did not return it because I couldn't be bothered.

Just the job
I like it and that's why it's got 5 stars from me. If you like G-Shocks then you know what you want otherwise don't buy one as it's really just a watch! Tough as nails and keeps working all day, unlike me..

Good watch
1st G-shock I've bought & I love it. I personally prefer a minimal type of watch, normally when you buy that type of watch the build quality isn't great but this watch is sturdy and really robust. I did find the buttons difficult to use on set up and light could be a little brighter. Overall a great watch

Excellente montre
Rien a redire, sa réputation la précède. Donne l'heure et le jour et plusieurs fonctionnalités. Très résistante, 8 mois d'utilisation intensive et pas une égratignure. Le seul defaut serait les réglages, pas très intuitifs, et qui nécessitent le manuel d'utilisation. Le prix est clairement justifié, et rapport qualité prix excellent.

Good value G Shock.
I believe that this model is discontinued in North America. You may be able to find a style that you like at a retailer and if you want it, I suggest you buy it. Amazon delivery was exactly as expected. Watch is very beautiful with a blacked out dial with red accents. If you like a digital display, this watch is not for you. The digital display is very small. Very light and comfortable to wear with not having a bulky G Shock. You won’t break the bank to purchase this watch, so it is a great everyday beater or vacation watch.

Sehr gute Armbanduhr für Alltag
Ich war schon seit Schulzeiten Fan von Casio-Uhr und nachdem meine letzte 2 Uhren wegen Alter (8-10 Jahre) kaputt gegangen sind, habe ich mich auf die Suche wieder nach Casio Uhren gesetzt. Casio G-Shock war eine von den Varianten und die schwarz-orange Version fand ich richtig schön und minimalistisch. Nach dem Erhalt muss man 5 Minuten widmen und die Uhr einrichten (am besten ein Youtube-Tutorial anschauen) da wird es genau erklärt wie und was man da klicken muss. Bin zufrieden

Muy bien
El reloj es ideal, era para un amigo y le encantó. Me resultó extraño porque llegó con una alarma establecida a las 17:00, se puso a sonar dentro de la caja.
