Abstract
A method for fabricating pallets for an escapement system concerns the field of escapement systems for timepieces. The method includes forming integrally, using a first material, a lever of pallets. A first end of the lever includes a dart. A second end of the lever includes two arms each for receiving a pallet stone. The method includes over-moulding a second material different from the first material on the first end of the lever in order to form a pallets fork. The method includes mounting the pallet stones and a staff to enable the pallets to be rotatably mounted.
