I wore it for 6 years until the battery ran out, during this time I changed the strap 3 times - this is its weak point. The rest of the watch is just perfect (at least for me). Now I bought the exact same ones again and I'm very happy with it :) Pros below: Simple, comfortable, stylish, practical. Magnificent backlight. The watch itself is very high quality, which cannot be said about the strap (but it is very comfortable). The battery lasts for 6 years with sufficient intensive use (backlight, alarm clock). Waterproof not only from raindrops, as stated in the instructions, but you can even swim in them. They can also be dropped, hit, thrown. Cons: Once every 2-3 years, you need to change the strap, because it breaks. It looks like he was specifically programmed for it. But all these 2-3 years will be reliable and strong.
