This is an amazing watch. I used the same watch for 15 years and in 2025 I bought it again after the older one was damaged due to some aggressive chemical. I live in the East Coast of the US and I have friends and family in different parts of Europe. I regularly check the time over there. I use the timer for when I am brushing my teeth. I use the stopwatch when I brew coffee. I use the alarms for my daily short walks and to wake up. I had to remove two sections of the strap to make it a good fit for my wrist. You may need to do that as well. All around it is just an excellent watch. Casio is of course amazing with quality. I would recommend it to anyone. I know smart watches are getting more and more common but trust me, one less device to charge regularly is a better improvement in your life than anything else.

Good watch but misadvertised with wrong color

Color: Black, Style: AE-1000W-1AVDF

So far I really like this watch but you get a different watch color than pictured. The watch is the AE-1000W-1AVDF which shows silver/grey and black, with a blue world map. You don't get that as the 1AVDF model is an all black watch with a grey world map. The watch is just as nice but not what was shown and sold as, so BEWARE.
