AbstractA watch winding and time setting assembly comprises a crown body having an axial passage extending therethrough, and a push-button located in said axial passage. Said passage comprises a first portion of circular cross-section in which is located a cylindrical head of the pushbutton, a second portion of non-circular cross-section greater than the diameter of the first portion and in which a shoulder of the pushbutton is keyed, and a third cylindrical portion having a diameter no smaller than the second portion, which third passage portion has a sleeve fixed therein for receiving and retaining a compression spring. Said spring biases said shoulder into abutment with the lower edge of the first passage portion, and the sleeve acts as a limit stop for said shoulder portion.
