    This review is about the strap colour: Green

    I've had it for about a month, and I also own another G-Shock, and just like all the others, this is a fantastic watch for everyday use, swimming, and rough use at work!

  • This review is about the strap colour: Black

    Whatever I say is not enough for this G-Shock; after so many years of production, almost 15 years, it still sells as if it was released today. Simply, if you love this kind of watch, you must have it.

    This review is about the strap colour: Black

    My father bought the watch when I was born, in 2009, and this May he gave it to me after 16 years, having only changed the battery twice. This particular model is literally the "beetle" of Casio

    This review is about the strap colour: Black

    I must have had it for almost ten years without regretting it, and it hasn't had any issues. I constantly put it on and take it off, and I'm still on the first strap, but the ring that holds the "tail" has been broken for a while now, and overall it's not really worth much anymore.

    It consumes batteries relatively quickly, especially if you frequently use the (very nice) lighting. I change them myself without any problem.

    Its mechanism is not particularly accurate, mine goes forward very quickly.

    I love it, but I think 110€, which I see it is currently priced at, is too much.

    I have changed its lights for ten years. I got tired of hitting it, mistreating it, venting my frustration. I will get another one because this one endures a lot !!!

    This review is about the strap colour: Black

    Awesome watch. I have had it for 4 years, the battery has only died once. It has taken a lot of beating because I don't respect it at all and I wear it constantly, value for money!
    The only negative is that it loses a few seconds per week and you have to adjust it every now and then.

    This review is about the strap colour: Black

    Excellent watch! Very beautiful and sturdy, but also comfortable on the wrist. I have had it for 6 years and have enjoyed it greatly! It hasn't suffered any damage, even though I wear it every summer in the sea. I wear it everywhere and always. At work and on outings! The only thing I could say is that the battery lasts me about 2 years.
