To provide a chuck, capable of retaining a micro-sized workpiece, securely retaining workpieces of various surface forms, and coping with a plurality of workpieces of different surface forms by a single chuck, and a method for manufacturing a timepiece, capable of decreasing the number of chucks to reduce the cost, and shortening adjusting time to improve productivity.

In the chuck 1, a tip surface 4a of a straw member 4 is applied to the workpiece X, so that air is sucked from the base end side of the straw member 4. The workpiece X is thus sucked by the tip surface 4a of the straw member 4, so that the workpiece X is retained. The straw member 4 includes a plurality of pipes 40 which are disposed along an axis L to be movable along the axis L.
