How black dial NOOB Factory Rolex Sky Dweller m326938-0004 Super Clone Watch Saros system operates

Saros system: The key is a smart planetary gear set. Gears inside the movement mesh with a fixed wheel. This tells 30-day months from 31-day months. The NOOB Factory Rolex Sky Dweller m326938-0004 Super Clone Watch copies the original logic and switches the annual calendar by itself.
Adjusting: Just turn the bezel to a certain position. Then you can set the month or date separately. The movement module drives all the complex logic. No extra power needed.
Why people care: NOOB factory strengthened the key drive gears. This fixes the easy-wear problem of the annual calendar module. So it keeps complex functions and still runs very reliably for a Rolex replica watch. It is a top-level product in the replica world.
