If you need a watch to keep track of the time, this is your choice. They are inexpensive, the original Japanese brand, high accuracy. For young people it is the best, especially for those who love minimalism ;-) Some pros: Light, compact, almost not felt on the arm, I sleep peacefully with them, do not interfere) Uniform luminescent screen backlight, alarm clock, stopwatch Different cons: It is possible that the strap will loosen up over time. It was precisely because of this that I changed the last f-91w watch to these. May be too small for a large hand.
