发明名称 TIMEPIECE MOVEMENT COMPRISING A RUNNING EQUATION OF TIME DEVICE
摘要 The timepiece movement comprises a running equation of time device having a pipe (113) provided to support a minute hand for solar time mounted concentrically to the minute and hour hands for civil time, an equation of time cam (101) rotatably driven by the movement at the rate of one revolution per year, and a correction mechanism provided to periodically adjust the angular displacement of the minute hand for solar time in relation to the minute hand for civil time as a function of the angular position of the equation of time cam.
