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.

Authentication guide
The Sub 200 is Doxa's entry diver, offered in multiple colorways. It uses a steel case and is rated to 200m. The Sub 200 is the most accessible Doxa and the most straightforward to authenticate: the inner bezel dive scale and correct colorway typography are the key checks.
