Product almost as described, good quality for the price, very well packaged, fast delivery if it was not stopping at customs, good seller. Regarding the first impressions, there is no blue lighting at 12 o'clock (it is preferable to have green as in other positions than not to have it), after the first 10 hours of use it seems accurate, a little heavy mainly due to metallic bracelet. Regarding the adjustment of the bracelet and following the direction indicated on the bracelet, it was not easy - the tool provided removes some pins easily and others do not come out and bends the tip of the tool (wrench or pins problem ???). In the manual the indication of 5atm is not to swim contrary to what it says in the discretion that says it is to swim. Even in spite of some of the less positive issus, I am satisfied with the purchase.
It has the same functions as a mechanical watch. It has a calendar, a chronograph ring, a luminous, and a waterproof function. The most important point is that its price is much cheaper than a mechanical watch. Of course, the only difference between it and a mechanical watch is , The battery needs to be replaced to keep the hands working properly. This is a great quartz watch, worth buying
