Although it's a larger men's watch (41mm), it fits my wrist comfortably. The strap is made of an extremely soft and flexible silicone that almost doesn't feel like wearing the watch. I love this watch because the strap says what NASA is doing. The face is mirror smooth and shiny. I want a day/date function or just a day function. But I'm just picky. Overall I would recommend this watch to men, women and teenagers.
