Lubricating oil composition for timepiece and timepiece

A lubricating oil composition for a timepiece, comprising a lubricant component (A) containing at least one base oil (A1) selected from a polyol ester (A-1), a paraffin-based hydrocarbon oil (A-2) having 25 or more carbon atoms and an ether oil (A-3), at least one antiwear agent (B) selected from a neutral phosphate ester and a neutral phosphite ester, and an antioxidant (C), wherein

• the total acid number of the composition is not more than 0.8 mgKOH/g,
• the antiwear agent (B) is contained in an amount of 0.1 to 15 parts by mass based on 100 parts by mass of the lubricant component (A), and the antioxidant (C) is contained in an amount of 0.01 to 3 parts by mass based on 100 parts by mass of the lubricant component (A), and
• a diphenylamine derivative (C-1) represented by the following general formula (c-1) and a hindered amine compound (C-2) represented by the following general formula (c-2) are contained as the antioxidants (C),
• wherein Rc11 and Rc12 each independently represent a straight-chain or branched alkyl group of 1 to 10 carbon atoms, and p and q each independently represent an integer of 0 to 5 with the proviso that p and q do not represent 0 at the same time,
• wherein Rc21 and Rc22 each independently represent an aliphatic hydrocarbon group of 1 to 10 carbon atoms, and Rc23 represents a divalent aliphatic hydrocarbon group of 1 to 10 carbon atoms.
