Proud of my watch.
Color: G5885-silver-red, Color: G5885-silver-red
I purchased two of these and I am pleased so far.I was able to resize the band without any problems.They look good and I’ve received a few unsolicited compliments.IMHO they are well worth the 35 bucks or so I spent on them.Heck two of my buddies wearing r.l.x’s noticed them right off the bat.I just smiled and said thank you very much. P.s.I could buy and sell my two friends many times over so didn’t bother me when they ask me the price.Proud of the good watch for the money.

Not for me
Color: G5885-silver-red
Unfortunately, this watch was a huge disappointment. Regardless, it was probably worth the price. I just didn’t feel right with it on my wit wrist. I’ll take a Timex any day over this.
