Great watch for the money
Color: Stainless Mesh/ Blue Dial
Looks great. I swapped out the band for a leather strap. Nice watch, well designed. My other eco drive has been going strong for 15 years or so without a hitch. So I have high expectations for this one.

Flimsy, small face
Color: Stainless Mesh/ Blue Dial
This watch doesn’t feel like the typical eco drive. The face is small, it’s very light and the mesh band was a pain to clasp. I returned it the day I got it.
