FIELD: physics.
SUBSTANCE: structure comprises a thermal motor with the capability of converting temperature difference in various points of space into motion of a wristwatch mechanism, in particular, a thermal motor with the capability to convert difference of temperatures near the surface of a watch user's arm and ambient temperature into motion of the wristwatch mechanism in the form of a thermal motor of a heat Stirling motor of gamma type, rotor type or free-piston type. The wristwatch mechanism with an automatic drive, and the mechanical wristwatch comprises the specified automatic drive. According to the method of automatic actuation of the mechanical wristwatch, the watch drive is a thermal motor with the possibility to convert difference of temperatures in different points of space in the watch body into motion of the watch mechanism, in particular, they use a thermal Stirling motor with the capability to convert difference of temperatures at the surface of the user hand at the side of the back cover of the watch and air temperature at sides of the watch body or at the side of the dial plate into motion of the watch mechanism.
EFFECT: simplified design of a watch drive, automatic winding of a watch mechanism motor and provision of automatic winding of a watch mechanism even with no movements of a user in an automatic drive of a wristwatch mechanism comprising a source of motion energy as a source of motion energy.
