FIELD: physics.
SUBSTANCE: watchwork (1) includes a plate (10) and a bridge (11) which support a case (1), which includes a mainspring (2) of the case, situated between a drum (3) and the receiving surface (5) of the core (4), and a cover (7) perpendicular to said drum (3). Said spring (2) is made of a cobalt-nickel-chromium based multiphase alloy having Young's modulus of 200-240 GPa, and a shearing modulus of 80-100 GPa, and has width-to-thickness ratio of 3-23, and the maximum radius of said core (4) made of steel or stainless steel relative to said axis of rotation (D) is less than nine times the maximum thickness of said spring (2). Said watchwork (1) also includes means of limiting oscillatory displacement, which includes a gasket washer (70), which is independent from said core (4) and is guided by the shoulder (44) of said core.
EFFECT: smaller diameter of the core and easy dismantling of the mechanism when replacing the mainspring.
