Marker Spacing
Photography can materially change how marker spacing appears on 179173GSUNLINE. Control angle, focus, white balance and reflections before treating an image difference as a manufacturing difference.
Evidence Question: Fake-Watch Screening
When screening 179173GSUNLINE for possible fake or replica characteristics, make fake-watch screening testable: identify the disputed component, obtain evidence that isolates it, and compare it with the correct generation instead of relying on a one-tell verdict.
Evidence Question: End-Link Fit
179173GSUNLINE should not inherit a conclusion about end-link fit from a visually similar reference. Generation and configuration must be established first because small reference changes can alter details that matter to identification.
Rehaut Alignment
Photography can materially change how rehaut alignment appears on 179173GSUNLINE. Control angle, focus, white balance and reflections before treating an image difference as a manufacturing difference.
Crystal Profile
Place crystal profile within an evidence hierarchy for 179173GSUNLINE. Repeatable structure and function normally deserve more weight than lighting-sensitive appearance, and uncertainty should remain explicit when the available evidence is weak.


















Brondan Holl –
This version appealed to me because it has a fairly clear design with a few details that make it different. The listed power-reserve specification is another detail I paid attention to because I prefer knowing what the movement specification is. At this stage, I’m pleased with the choice.
