Claim 1
Independent Claim
227 words
A watch having a watch movement, comprising a winding stem movable radially with respect to said watch movement, between a first, a second and a third position, a pull lever pivotally mounted about a fixed axis and operatively connected to said winding stem, a correction lever operatively connected to said pull lever, a correction wheel engaging a square portion of said winding stem and operatively connected to said correction lever, a setting wheel pivotally mounted about a fixed axis and engaging said correction wheel when said winding stem is in one of said first and second positions, wherein said correction lever is pivotally mounted about the same axis as said setting wheel and said correction lever has associated therewith a toothed gear, said toothed gear engaging said setting wheel, minute gear means to set both a minute and an hour hand, and hour gear means to set said hour hand alone without displacing said minute hand, said correction lever being operatively connected to said pull lever to provide engagement of said toothed gear with said minute gear means when said winding stem is in said first position and to provide engagement of said toothed gear with said hour gear means when said winding stem is in said second position, whereby in said third position of said winding stem said correction wheel is disengaged from said setting wheel.
