The complication of the Tellurium is made possible through the creation of a module designed and conceptualized by Théo Auffret, manufactured in Switzerland, and assembled in Paris. The entire complication is built on an additional plate, which is connected to the Soprod P024 movement.

As the caliber's date changes, the star wheel with 31 teeth, carrying the date disc, will advance two star wheels with 12 teeth each. The first of the two wheels advances the months, and the second is dedicated to the Tellurium complication.

The planets are fixed on a sapphire, which is connected to a ring with 365 teeth, corresponding to the number of days for Earth to complete one orbit around the sun.

The moon is fixed on a pinion, which is connected to the fixed wheel. This is visible from outside the dial. Adjusting the watch, particularly the real-time position of the moon, is achievable through the quick date function. It will only require fine-tuning with the time setting, depending on the number of days in the month (30 or 31).
