WATCH TO WHICH ULTRALOW FRICTION LUBRICATION ASSEMBLY IS APPLIED

摘要

PROBLEM TO BE SOLVED: To provide a watch to which an ultralow friction lubrication assembly is applied.

SOLUTION: The present invention relates to a watch to which an ultralow friction lubrication assembly is applied. The watch includes: a first member which is slidable with respect to a second member and whose sliding surface has a chemical affinity for a OH group; and one or more types of oxygen-containing compound, located on the sliding surface of the first member, which can form a tribofilm attached to the sliding surface of the first member typically by a hydrogen bonding interaction. The second member has a similar OH terminal sliding surface, herein preferably, the interface supported by the oxygen-containing compound (lubricant) between the respective sliding surfaces of the first and second members have a H- and/or OH-terminal interface and cause repulsion between the respective sliding surfaces of the first and second members.
