The watch Is beautiful, keeps time & date well and seems to be made of quality materials
Color: A1 - Blue / Brown
First off I have not had a watch in 20 years since I use my phone for the date and time. I decided to try using one again and love not having to retrieve my phone to check the time.
The watch is beautiful and I love the look of the gold with the blue face and brown band. It works great and appears to be of the same quality as the Seiko watches that I use to own. I tested the face and tried to scratch a small area with a sharp object. I would not scratch so it is either glass or a crystal. the metal seems to be of good quality and the band is comfortable and feels like leather.
Overall I am happy with it and will update this review if the situation changes.

Nice looking watch with day and date
Color: A5 - Black
This watch has a nice black face and looks like it is high quality considering the price. I guess time will tell how durable it is. The only thing I am not as pleased about is the band which is stiff and is not as comfortable as another watch that has a leather band.
