Embodiment Construction

[0028] figure 1 A shows a perspective view of the movement part of the timepiece of the present invention. The same movement part is in Figure 2A and Figure 3A is shown in side view, and in Figure 2B and 3B Shown in top view. here, as in figure 1 In the case of Figure 2A and Figure 2B The adjustment shaft 16 in the normal position, while in the Figure 3A and 3B The adjustment shaft 16 in is adjusted axially outwards to the adjustment position. If adjusting shaft 16 as in figure 1 , 2A in its normal position as shown in 2B, the movement operates normally. The details of the functioning of the movement are known to those skilled in the art and are not the subject of the present invention, so they are not described in detail. For the meaning of reference symbols not explained in detail below, see the list of reference symbols associated with the description of the figures.

Abstract

The invention relates to a timekeeper, at least having a minute hand, a seconds hand and a clockwork mechanism with a mechanism for adjusting the minute hand. The mechanism comprises an adjusting shaft moving between a conventional position and an adjusting position in an axial direction, the adjusting shaft is coupled with a center-wheel group of the clockwork mechanism such that rotation of theshaft adjusts the minute hand. The adjusting shaft co-operates with a zeroing mechanism, the zeroing mechanism drives the second hand in a zero position when the adjusting shaft moves in the axial adjusting position and locks the seconds hand in the zero position when the adjusting shaft is in the adjusting position, and releases the seconds hand when the adjusting shaft moves in the conventionalposition again. According to the invention, the center-wheel group of the clockwork mechanism has a lock mechanism, the lock mechanism can obtain 60 locking positions, so that the minute hand can move among 60 positions the minute hand by rotating the adjusting shaft in the adjusting position, and each of 60 positions corresponds one minute scale.

Description

technical field [0001] The invention relates to a timepiece having at least a minute hand, a second hand and a movement with a mechanism for adjusting the minute hand. Said mechanism comprises an adjustment shaft / stellwelle movable in the axial direction between a normal position and an adjustment position by pulling or pressing in the crown. In the adjustment position, the adjustment shaft engages with the minute wheel set of the movement, so that rotation of the adjustment shaft causes a movement of the minute hand. Furthermore, the adjusting shaft cooperates with a zero-setting / resetting mechanism, which drives the seconds hand into the zero position when the adjusting shaft is moved into the adjusting position and locks the seconds hand in this zero position while the adjusting shaft is in the adjusting position , release the second hand again during the movement of the adjustment shaft back to the normal position. Background technique [0002] Timepieces with such mec...
