Feels cheap, not good for old eyes.
The watch seemed to work good. But it felt cheap, and I was looking for something with better illumination and easier to read. I ended up returning it.

Good watch, worth the purchase
Color: Tan/Blue/Silver-Tone
My $10 watch finally died after years of trouble free service. I ordered not one but 2 different ones to replace it and they were both defective. I ordered this one because of Timex’ reputation, the large watch face, no day/date functions, and I liked the looks. All for less than $60. It has been working faultlessly since I purchased it.

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.
