For those who don’t know, GPHG stands for High Horological Grand Prix and the guidelines of each category are the following:

**- Calendar and Astronomy**: mechanical watches comprising at least one calendar and/or astronomical complication (e.g. date, annual calendar, perpetual calendar, equation of time, complex moon phases display, etc.). Additional indications and/or complications are admissible. One-of-a-kind models are not eligible for this category.

**- Time Only**: watches displaying only analogue time indications (hours, minutes, seconds) by means of two or three hands on a solid dial, devoid of any other type of indication, complications or gemsetting. One-of-a-kind models are not eligible for this category.

**- Chronograph**: mechanical watches comprising at least one chronograph indication. Additional indications and/or complications are admissible. One-of-a-kind models are not eligible for this category.

\- **Essential:** watches displaying one or several of the following indications: hours, minutes, seconds, date (day of the month), power-reserve indicator, classic moon phases, day/night indicator. They may feature a digital or retrograde display and they may not fall within the respective definitions of the *Time Only*, *Complication* and *Gemset* categories. One-of-a-kind models are not eligible for this category.

A true feat of strength from PF at GPHG
