Great little watch for the money
Color: Brown/Brown/Natural, Color: Brown/Brown/Natural
I've just received the watch, so I can't comment on the durability. Hopefully it lasts a long time, because I really like this watch. My first impression of the watch was that it was a bit smaller than what I'm used to wearing. But when I put it on, it seemed like a good fit. The band looks great and feels pretty comfortable. I like the color of the band, and of the watch face itself. Even with my older eyes (56 years), I can easily read the time. The date, not so much. It's pretty tiny. Setting the time and date was pretty simple. And even though I knew this watch had it, I stumbled upon activating the Indiglo feature by accident. It's pretty cool, btw.
Some people have commented on the ticking. The environment in which I wear the watch is never completely silent, even at home. I have to put the watch pretty close to my ear to hear it, and I have good hearing. When I do hear it, it's actually a pleasant sound to me.
To sum it all up, I love this watch! I actually do a little watch collecting. This is by far the least expensive watch I own. And now, the one I'll wear the most.
