Case Silhouette — Community Qc

William Walker –
I had a pretty specific look in mind when I started shopping. Once I saw it in normal lighting, date display and automatic movement made more sense than it did on screen. The buying experience was fairly simple, with no particular issues that stood out. The Rolex styling is close to what I was looking for. So far, it has met my expectations.
