<P>PROBLEM TO BE SOLVED: To provide a C-ring for watch processing oil composition in which the strength adjustment can be easily performed, compounds of sulfur, phosphorus or the like are not used as an additive, the manufacturing method is easy, that is economically advantageous, and in which a process defect does not arise by the volatilizing at the time of processing, and to provide the manufacturing method of the same, a C-ring for a watch processed using the same, and a watch. <P>SOLUTION: The C-ring for watch processing oil composition includes: a chlorinated hydrocarbon compound (A) in which average at least 21 and at most 24 of hydrogen of the hydrogen of a 26C saturated hydrocarbon wax are substituted by chlorine; and a chlorinated hydrocarbon compound (B) in which average at least 5 and at most 7 of hydrogen of the hydrogen of a 14C normal chain saturated hydrocarbon are substituted by chlorine, wherein the content of (B) to (A) is at least 3 wt% and at most 20 wt%, and is obtained by that (B) is heated between 40 and 110, then (A) is added, and the mixture is stirred to be dissolved, the C-ring for a watch is processed to be obtained, and the watch is manufactured using the same. <P>COPYRIGHT: (C)2013,JPO&INPIT |
