Abstract
To provide a watchmaking C-ring processing oil composition that suppresses die wear and reduces the occurrence of scratches in the resulting watchmaking C-rings, even when the process is repeated over a long period of time during the manufacturing of watchmaking C-rings by drawing. [Solution] The watchmaking C-ring processing oil composition of the present invention comprises a chlorinated hydrocarbon (A1) which is solid at 25°C, has a melting point of 110°C or less, has 18 to 28 carbon atoms, and has a chlorine atom content of 68% to 72% by mass, and a chlorinated hydrocarbon (A2) which is liquid at 25°C, has 18 to 20 carbon atoms, and has a chlorine atom content of 48% to 52% by mass.
