Testing Movement Layout
For 178240, a useful test of movement layout starts with evidence quality. Request a component junction view, then cross-check the relevant spacing; if perspective changes the finding, keep the result provisional rather than turning it into an origin claim.
Finish Boundaries on This Reference
Finish Boundaries becomes valuable on 178240 when it is kept independent from provenance. Map the physical or functional mechanical sequence; documents, seller claims and factory attribution belong to different evidence categories and should not rescue a weak observation.
Evidence Channel: Lug Curvature
178240 should not inherit a conclusion about lug curvature from another watch in the same series. Benchmark the feature within this exact White, 31mm, and Stainless Steel combination; reference-generation differences can otherwise masquerade as defects.
Pusher Construction
178240 should not inherit a conclusion about pusher construction from another watch in the same series. Record the feature within this exact White, 31mm, and Stainless Steel combination; reference-generation differences can otherwise masquerade as defects.
Hand Reach on This Reference
Treat hand reach on 178240 as construction evidence rather than decoration. Follow the geometry across adjacent components and look for a repeatable pattern. Wear, polishing, servicing and image reflections are alternative explanations that need to be separated.

I wasn’t totally sold by the photos, but I decided to try it. The overall design is noticeable without being over the top. Customer service answered my question before I ordered, which helped. I can see myself getting a lot of use out of it.
