Robert Martinez –
This was one of those purchases where I changed my mind a few times before ordering. What I appreciate most is that diamond markers and date display doesn’t overwhelm the rest of the piece. There was a little more detail to consider than I expected, but that helped me make a more informed choice. I’m satisfied with it at this point.
