Problems solved by technology

[0006] However, according to the conventional self-winding timepiece, the self-winding mechanism including the oscillating weight, claw lever and the like is arranged above the wheel train mechanism, and thus it is difficult to make the movement thin
[0007] In addition, according to the conventional self-winding timepiece, the switching device and the balance with hairspring are arranged away from each other, and thus it is difficult to arrange the gear train setting device for setting the balance with hairspring on the movement

Embodiment Construction

[0037] Embodiments of the self-winding timepiece of the present invention will be described below with reference to the drawings.

[0038] (1) The structure of the top side of the movement:

[0039]First, a description will be given of the structure of the top train, escapement and speed control mechanism arranged on the "movement" top side (main plate side opposite to the dial) in the self-winding timepiece of the present invention. "Movement" means the mechanical body of a timepiece, which includes the mechanisms that drive the timepiece.

[0040] refer to Figure 1~3 and Figure 7-9 , in the self-winding timepiece of the present invention, the movement 100 includes a main splint 102 , and the main splint 102 includes the bottom plate of the movement 100 . The winding stem 310 is rotatably coupled in the winding stem guide hole of the main plate 102 . Dial 104 ( figure 1 , 2 , 8 and 9 represented by phantom lines) are connected on the movement 100.

Abstract

Provided is a self-winding timepiece having a thin and small-sized movement in which a train wheel setting apparatus for setting a balance with hairspring is efficiently arranged at the movement. A self-winding timepiece includes a main plate, a time indicating wheel, a winding stem and a switching apparatus. A movement barrel complete is arranged on a top side of the main plate and arranged to overlap a main plate reference horizontal axis line between a first region and a fourth region. A balance with hairspring is arranged on the top side of the main plate and arranged to overlap the main plate reference horizontal axis line between a second region and a third region. The switching apparatus is arranged on a back side of the main plate. A train wheel setting apparatus includes a train wheel setting portion for setting the balance with hairspring by penetrating the main plate. A portion of the train wheel setting portion of the train wheel setting apparatus for setting the balance with hairspring is disposed in the second region and a rotating center of the train wheel setting apparatus is disposed in the second region.

Description

technical field [0001] The present invention generally relates to a self-winding timepiece with a wheel train setting device. In particular the invention relates to a gear train setting device operated by rotation of a setting lever, comprising a movement of small size and / or thin size. Background technique [0002] (1) The conventional self-winding timepiece disclosed in Patent Document 1: [0003] Traditional self-winding design includes main plate, center wheel & pinion, movement barrel assembly, escapement speed control device, conversion device, dial and oscillating weight. The movement barrel assembly is arranged on the side of the main plate opposite the dial and provides a center of rotation in the first area. The escape wheel & pinion and the pallet fork are arranged on the side of the main plate opposite the dial and set the center of rotation in the third area. The balance with hairspring (70) is arranged on the side of the main plate opposite the dial and is a...
