PROBLEM TO BE SOLVED: To reduce the wear of the friction surfaces of the joints of straps for a watch with metal links. SOLUTION: This strap with articulated links, in particular for a watch, comprises at least three adjacent rows of links offset from one adjacent row to another, in which at least one of friction surfaces (3, 13, 23-163) of each joint is made of a material of which the hardness is equal to or larger than 800 HV. The bearing surfaces (3, 13, 23-163) is in contact with at least one of joint elements (5, 15, 25-165) having at least one friction surface made of a second material selected from the following materials: ceramic, ceramic-metal composite, amorphous carbon, stainless steel without nickel, cobalt alloy, gold or gold alloy, platinum or platinum alloy, platinoid or platinoid alloy, titanium or titanium alloy, capable of reducing the frictional wear with the friction surfaces (3, 13, 23-163).
