Entry to the Grand Prix d'Horlogerie de Genève is voluntary and made by the brand. An entry is a watch registered for that year's competition, not a jury verdict, and several large houses including Rolex, Patek Philippe and Omega do not take part at all.
The Petite Aiguille category at GPHG 2023 held 30 entries. These are the other 29.

Seamless bracelet-to-case integration is the Octo Roma design signature; any gap or step at the lug interface is a non-genuine indicator.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| bracelet | Seamless lug-to-case integration | Bracelet integrates seamlessly into case at lug interface; no gap or step visible | Gap or step at lug interface; non-genuine or aftermarket bracelet |
| case | Octagonal case edge finishing | Consistent brushed and polished finishing on all octagonal facets; sharp edge transitions | Rounded facet edges; over-polished; blended finishing |
| caseback | Cal. BVL 191 designation | Cal. BVL 191 in-house auto on caseback; consistent with Octo Roma specification | Wrong caliber; non-genuine caseback |
The Octo Roma is the integrated-bracelet sport variant in the Octo family, using the in-house Cal. BVL 191. The octagonal-on-round bezel-case interface is the defining visual, and the bezel finishing complexity is the primary authentication lever.
