Claim Text:
1. A watch comprising: a first substrate surface; and a second substrate surface; wherein at least one of the surface of the first and second substrates is covered with a low friction device that reduces a friction coefficient and wear of the first substrate surface against the second substrate surface, the low friction device comprises a solvent and a coating comprising polymer brushes bonded to the surface and swollen by solvation of the solvent, wherein the solvent is selected from the group consisting of an ester lubricant, an alkane lubricant, an alkyl-aromatic lubricant, an ether-alcohol lubricant, a vegetal oil, an animal oil, a polyalcohol and an ionic liquid, and wherein the solvent is trapped within the polymer brushes and is ejected from the polymer brushes when the polymers brushes are subjected to pressure in such a way that the friction coefficient and the wear of the first substrate surface against the second substrate surface are reduced due to the ejection of the solvent.
