The case is coated by Dia-shield coating. This makes it highly scratch resistant.
The top of the crown on this wristwatch is made from a natural stone onyx.
The belt is 17mm wide. This is not a common belt width, but you can easily find more on eBay. You can enjoy a different feel by changing the belt.
I think this works wonderfully as a women’s watch as well. In fact, it may not suit a man with thick arms...
