Fake-Watch Screening Question
Use fake-watch screening question to separate counterfeit-language claims from observable evidence on 278240-0017. A so-called clone may reproduce obvious styling while differing in less visible geometry or mechanics, so the assessment should remain multi-factor and reference-specific.
Marker Rhythm on This Reference
The stated Automatic creates another route into marker rhythm on 278240-0017. Where mechanically relevant, record operation or architecture first; movement labels and decorative markings remain secondary.
Bracelet Taper
Instead of starting with overall appearance, examine 278240-0017 through bracelet taper. A neutral close-up can expose the relevant relationship while reducing perspective and reflection errors.
Testing Clasp Hinge
Instead of starting with overall appearance, examine 278240-0017 through clasp hinge. A side elevation can expose the relevant relationship while reducing perspective and reflection errors.
Generation Consistency on This Reference
278240-0017 should not inherit a conclusion about generation consistency from another watch in the same series. Evaluate this exact Blue, 31mm and Stainless Steel configuration against the matching generation.




























Jason Wright –
I mainly bought it because I liked the look. The overall design is probably my favorite part. Overall, I’m pleased with it.
