No round has proven an image for this record. An image is written only where the brand’s own page ties the picture to the reference — by its structured data, or by the reference appearing literally in the asset URL. Position in a gallery is not proof, so where nothing proved the pairing nothing was stored.
Movement
Ronda 715 Li
Grade not disclosed by the source; the edge points at the grade-unknown execution.
The brand publishes a caliber name of its own and no source in this corpus states which physical design it contains, so this edge sits on the designation rather than on a caliber. The claim is not weaker for it — it is simply narrower than a design.
