I still maintain that the F91W solved the "watch problem" for just about everyone in the world. Ten USD, keeps date and time, has an alarm, illuminates, water resistant, and will last 7 years on battery. The value is insane.
i opted for another watch, still from casio (W-735H-1AVDF, 20€ from amazon) and while this is again a great value... the strap broke again. on this last one i got an unofficial strap that's working okay, but i don't know for how long.
