Boyfriend looks good in them

Bought these for my boyfriend and he looks amazing in them! They fit his body so well. Quality is nice and soft. Boyfriend ended up getting them in multiple different colors.

Happy with my purchase

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 got used to that and does not bother me any. Louie Vazquez in San Antonio TX
