Great watch, amazing price
Color: Brown/Green/Silver-Tone, Color: Brown/Green/Silver-Tone
Solid piece for a great price. It’s eye catching but not too flashy. Looks very stylish but also with a hint of vintage appeal. I wear it atleast once a week in rotation with other watches. No issues and holds up very well. No issues since I’ve gotten it and loved the style so much that I went back and bought the white and gold faced timex too.

Good looking for a cheap watch, but will not pass for high end
Color: Tan/Blue
Looks pretty good for a ~$50 watch. I could tell a clear difference in quality versus a similar $125 Fossil watch though, which i preferred even considering the price difference.

Solid, dependable, and full of compliments
Color: Tan/Blue
I’ve worn this for a few months now and I get so many compliments on it. Like all timex watches the ticking is loud, but this is better than other ones I’ve had. For the price it’s solid. It’s my daily driver so I can keep my preferred watches for special occasions.
