Hand Stack — Genuine Study
Hand Stack evidence for 278384RBR-0030 uses hand stack against a same-generation genuine Rolex.

Crown Position — Genuine Study
Crown Position evidence for 278384RBR-0030 uses crown position against a same-generation genuine Rolex.

Only crown position observations from the matching 278384RBR-0030 generation receive direct comparison weight.
Case Silhouette — Construction Geometry
Case Silhouette on 278384RBR-0030 is treated strictly as case silhouette construction geometry. Repeated case silhouette shapes around the 31mm case are separated from color and gloss; case silhouette interfaces are recorded before cosmetic impressions. If case silhouette conflicts with the Purple or Stainless Steel configuration, that case silhouette conflict remains visible in the assessment.






























Matthew Jones –
This was one of those purchases where I changed my mind a few times before ordering. What I appreciate most is that white dial and diamond markers 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. The Rolex styling is close to what I was looking for. I’m satisfied with it at this point.
