Just a quick review of the Seiko solar,
so far so good, when I first got it, I put it under a incandescent and fluorescent light for 8 hrs, did not charge the battery well, so I let it charge for a day in a south facing window. That did it! been running well since.
I use this watch for work, I am a machinist, and wash my hands frequently thru the day. crystal is holding up well, and no water indications thru the stem. I will update the review after a few more months.

.... Update, it's been 3 1/2 years now, The watch is my daily wear, holding up well. keeps good time, minor scratches on the face. but I tend to bang into things all the time. band has held up well also. no problems! and the best part... not having to worry about the battery!
