A timepiece 1 comprising in particular a case 8 having a back cover 10 and a middle part 12 in a single piece, a control stem 26 co-operating with a pull-out piece 44, and an extractor device 48 enabling a part of the pull-out piece 44 to be raised to free it from the control stem 26. The timepiece is characterized in that the extractor device 48 comprises an extractor element 48 having a first branch 50 which slides in the movement 2 in a direction substantially perpendicular to the plane of the movement 2, the end of said first branch 50 being substantially facing the pull-out piece 44, and a second branch 52 which comprises a portion projecting from the periphery of the movement 2 to form a gripping arm. The extractor element 48 is free to move between a first position called the rest position, in which it does not act on the pull-out piece 44, and a second position called the operating position, in which the end of the first branch 50 pushes the pull-out piece 44 out of the groove of the control stem 26.
