    Отличный магазин, посылку прислали курьером на следующий день после заказа. Часы просто бомба не могу нарадоваться. В живую смотрятся куда лучше чем на фото.

    This watch model turned out to be the perfect birthday gift for my boyfriend. I was afraid that its realization would take longer, however, I was wrong. The watch arrived to me in express time. It is completely as described. To my surprise, the watch was 100% protected from external factors during transportation. The watch looks perfect with both casual and elegant attire. Hassle-free contact with the store and very friendly service. I believe it is well worth the price and heartily recommend its purchase.

    Already when selecting a watch for my needs, the size of the assortment and the service of the store impressed me very much. The color and design immediately appealed to me, so I decided to purchase it. A great description, parameters, photos and a 3D space image of the watch accurately illustrate the timepiece in person. However, after it arrived really quickly, I couldn't take my eyes off it, let alone take it off. Since then, the watch has been a part of me as well as my daily life. I received it in a rather simple box, containing all the documents and the watch in a metal case. All the components were well insulated against possible damage. The watch is light as a feather, but that doesn't make it so. It is very solid and measures the time accurately. All its functions are used and work flawlessly. The display is easy to read, the backlight works and the buttons work very lightly, so you don't have to "forcefully" change the watch mode. At first glance, you can see that the material of construction is not ordinary plastic, but high-quality plastic. Everything tightly enclosed in a spacious envelope, you can swim or dive in it without any problems. This was the first watch purchased on this site, but certainly not the last. I have already ordered another one, but this time as a gift for a loved one. I am waiting for the shipment so I can share my impressions!

    I have owned this watch for a week. The watch after unboxing looks better than in the picture. It took some time to set the time, date and day, but during that I could see how many functions the watch has. I like to relax actively, so I will test it in the mountains, at the pool, etc. I am sure that the watch will meet my requirements. I recommend buying this model and I am sure it will do its job 100%.

    I bought the watch almost a year ago, during this period of time I wore it almost every day. This model of watch is very versatile, it can be used for almost any situation. I used it everywhere, from wearing it to work to wearing it to some events or using it as a decoration for clothes. For the first couple of months the watch stayed in the same condition all the time, only recently - about 4 months - you can already see signs of use in the form of less saturation of color. It is a black watch, mine is already becoming slightly faded. The only thing to complain about this watch is the ease of scratching the strap, in my case it is quite visible. Other than that, this watch is, one could say, indestructible - once even accidentally fell from the 4th floor and nothing happened to it. The model has a lot of functions, it is waterproof, it is easy to change the settings in it and has a backlight on the dial. So far it works flawlessly, so far I have not replaced anything in it. I can wholeheartedly recommend this watch and without any worries encourage you to buy it.

    Watches as well as sauna are my passion. For a couple of weeks I've been thinking about choosing the right watch for the sauna - I wanted to know how much time I spend in the sauna. I'm more into smart watches, but picking up this G-SHOCK just stunned me - I really liked it. We were in the sauna together for the first time yesterday and it performed amazingly! Zero flare-ups of any kind, it didn't heat up much - I almost didn't feel it. It worked 100% well! I recommend.
