Happy with my purchase
Color: Black, Size: X-Large
The material is good quality and it did great in the gentle cycle of my washing machine. I hung it to dry, no dryer. Looks great.

Cheap and nice.
Color: Silver Black
It's heavy and easy to wind. Time is slightly fast, maybe a minute per day. Easy to resize. Great value.

it looks fantastic. There is nothing humble about this watch
Color: A Gold
It is a steal for the money, it looks fantastic. There is nothing humble about this watch. It makes its presence known. I see people get sight of it, then look away and come back and take a second long look at it One thing I would change.. the hands are not easily seen because they blend too much with the back ground. I got used to that and does not bother me any. Louie Vazquez in San Antonio TX

DOA - doesn't work.
Color: A Gold
Love the looks of this watch but I cannot get it to work. I think that it is mechanical, but I wind it and it only runs for one to 10 minutes and sometimes not at all. Am I doing something wrong?
