This is my 2nd ProMaster Eco Drive and it's stunning. Love the orange dial! It's solar, so no battery, and any light source powers it. My other is a green with the rubber band. If I have a beef it's that Citizen eliminated the ProMaster stamp on the back of the watch and the band is thinner with no depth markings that my older ProMaster had. Overall, it's a super solid watch. Citizen should pony up on the stamp on the back of the watch and upgrade the runner band.
