Mechanical Verification Brief — Dual-Time Display Logic
In this mechanical verification brief, keep dual-time display logic separate from provenance. Seller claims, documents and Clean Factory / VSF(VS Factory) belong to different evidence channels and should not rescue a weak physical observation.
Caseback-To-Midcase Transition Study
Place caseback-to-midcase transition within an evidence hierarchy for 179174BLRN. Stable geometry and repeatable function normally deserve more weight than lighting-sensitive color, gloss or one piece of printing.

Rabert Jocksan –
The first thing that caught my attention was the overall configuration. Customer-service information was useful when I wanted clarification before deciding. The case thickness of 10.4mm is worth noting alongside the 26mm; together they give a clearer idea of the proportions. For my purposes, this version makes a lot of sense.
