Evidence Question: Component Interfaces
This visual proportion study makes component interfaces the primary question for 278240-0015. Compare the feature with a verified same-generation genuine example, using the Dark grey, 31mm and Stainless Steel only where they materially influence the result.
Setting Sequence
Use setting sequence to test whether 278240-0015 tells one coherent reference story. The exterior configuration and movement claim should agree where this feature connects them; unexplained conflict deserves targeted follow-up.
Evidence Question: Bezel Registration
Place bezel registration within an evidence hierarchy for 278240-0015. Repeatable structure and function normally deserve more weight than lighting-sensitive appearance, and uncertainty should remain explicit when the available evidence is weak.
Visual Proportion Study — Date Typography
Use date typography to test whether 278240-0015 tells one coherent reference story. The exterior configuration and movement claim should agree where this feature connects them; unexplained conflict deserves targeted follow-up.
Investigating Fake-Watch Screening
When screening 278240-0015 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.


















Motthew Janes –
I like the combination of the Dark grey and Stainless Steel; it keeps the appearance consistent from case to bracelet. I kept coming back to this model when I compared the available options. I liked having the material and movement information spelled out rather than having to guess. The details are what make this version work for me.
