It has been 17 years that we developed the watch lubricant “AO-oil” which resolves the problems of existing watch lubricant, i.e. “gelation”, “metal corrosion”, and “temperature dependence of watch lubricant's viscosity”, caused by time decay. AO-oil has been developed especially with focusing on base oil and viscosity modifier, which extends the life of timepieces and enhances reliability. Furthermore, by enforcing higher lubrication and stability I found that the lifetime can be extended much longer. As to this development, an optimal additive has to be selected by focusing on antiwear/extreme-pressure agent and antioxidation agent. Hence, now I report on this new watch lubricant “AO-oil”.
