Adam Thompson –
This was one of those purchases where I changed my mind a few times before ordering. What I appreciate most is that black dial and rubber strap doesn’t overwhelm the rest of the piece. The ordering process was straightforward and I didn’t have any trouble finding the information I needed. The Rolex styling is close to what I was looking for. My first impression has been positive.
