Due to the fact that the watch was not available for viewing in my city (province), I decided to purchase only preceded by photos on the Internet and a few films about the watch available on the Internet. What can be said after unpacking is that the watch "live" looks exceptionally good. What immediately catches the eye is the attention to the smallest details and details, the quality of workmanship, the fitting of the whole and, above all, the overall appearance - the whole. There is nothing to tweak in this watch, not to refresh it anymore. You can immediately see that you are dealing with the "professional" G-Shock model, and after its construction it is not difficult to guess that it must be extremely physically resistant. The texture with the addition of carbon, clearly visible in the sun, gives an additional flavor. Appearance - its texture will certainly favor the fact that some small scratches or abrasions of the watch case will not be so visible. The watch belongs to the "big" type, but it is absolutely impossible to say that it is too big. Those who have dealt with the "G-Shock" models in the past will surely be pleased, and the new user of the rugged models - I think he will get used to it quickly. As for the functions. On board we have a thermometer, compass, barometer, altimeter, stopwatch, time synchronization and more (you can look at the technical description and find out exactly everything). However, I am about something else. Generally, apart from the alarm clock, stopwatch and, of course, the time and date, I will not need anything else except its guaranteed resistance to water, mud and dust. This is the basis for me when choosing a model, and this watch offers it, adding to it an incredibly good look (the rest of the features are a nice addition to me, which I probably only use occasionally). This is probably the nicest looking G-Shock model (at least in my subjective opinion). My oldest G-Shock is around 25-27 years old and I've been with these models for so many years. I had a total of 3 pieces (I choose each one carefully and use it for about 10 years). Each of my G-Shock works so far, nothing is wrong with them except for some light scratches on the case (the straps have been replaced), but after so many years you always want something newer, different-looking. Due to the fact that I chose this model with equal scrupulousness, I am also aiming for another at least 10 years of trouble-free use, to which the brand has gotten me used to. Well, since after nearly 30 years of use, the G-Shock brand has not let me down, I do not need to look for reliable watches. The store will probably not be satisfied with my opinion, because having a customer in me every 10 years is no attraction and no business. Well, well, the watch is not the cheapest one, most of them have to "bump" on it, make an effort financially, but I assure you that it is worth it, even for the very appearance, quality of workmanship and the manufacturer's assurances as to its durability, and after decades using other models, I am sure of these assurances. I had some concerns about buying the watch "in the dark", yes I know, it is possible to send it back in case of non-fulfillment of expectations. However, in fact, it turned out that the watch looks very "racial". It would be stupid to get rid of it, and if someone would wear it with such an intention, I advise you not to put it on your hand, because after applying it, it will not be easy to return it. I decided on the 1A1ER "color submodel" - according to my subjective opinion - this watch draws attention so much with its appearance and size and there is no need (for me) to add additional "screams" in the form of other color additions. The front ring in a color (or steel) of the "brushed" type, matte, with the buttons in the same color, and enough to give it a "scream" in the overall appearance, and at the same time the watch seems a bit more discreet (as far as possible) . PS. In stores, when I asked about the GWG-2000 model, I immediately received watches with similar functions (thermometers, barometers, etc.), available in a given store immediately, but I also decided on it because of its appearance (if not primarily). The proposed models - actually much cheaper and similar in functionality, but none of them presented themselves on hand, like the GWG-2000 1A1ER. Anyone proposed was far from him, too far to change his mind. I recommend it with a clear conscience.
