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 Homme category at GPHG 2020 held 35 entries. These are the other 34.

A 100-piece gold limited edition with the debut 9SA5 movement; provenance and movement inspection matter more than dial tells here
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| caseback | Limited edition numbering | Edition number engraved cleanly against the total run of 100; case serial matches accompanying paperwork; solid 18k gold caseback with Grand Seiko lion medallion | Stamped rather than engraved numbering; serial not matching papers; caseback material inconsistent with a solid gold case (too light, wrong color under testing) |
| movement | Calibre 9SA5 dual impulse escapement | Hi-Beat 36000 tick at 10 ticks per second; dual impulse escapement geometry visible and matches documented 9SA5 photos; Grand Seiko signed and finished bridges; 80-hour power reserve | Slower tick rate indicating a different calibre; escapement geometry inconsistent with 9SA5; undecorated or unsigned bridges |
| case | 18k yellow gold case and Zaratsu finishing | Gold hallmark/purity stamp present; alternating polished and brushed surfaces with distortion-free reflections; weight consistent with solid gold (noticeably heavier than a steel case of the same dimensions) | Missing hallmark; unusually light weight for the case size; blurred or rounded surface transitions |
