  "abstract": "A gripper device ( 100 ) for maintaining, centring, and/or clamping a micromechanical or horological component ( 200 ) in a clamping chamber defined by a clamp including at least one mobile jaw ( 2 ). At least a part of the mobile jaws ( 2 ) includes a reference surface ( 20 ) for frontal bearing of a component ( 200 ), and the gripper device ( 100 ) includes a vacuum generator ( 60 ) for creating the vacuum in the clamping chamber. Also, a method for fastening a micromechanical or horological component ( 200 ) in the clamping chamber of such a gripper device ( 100 ) according to which the component ( 200 ) is disposed on the reference surface ( 20 ), then a first maintaining by vacuum is carried out, then a second maintaining having a torque greater than that of the first maintaining by pivoting of the mobile jaws ( 2 ).",
