FIELD: machine building.
SUBSTANCE: impact-resistant bearing for chronometer comprises resilient structure (10) and central section (14), resting on said resilient structure, on said central section there is blind hole (16A), intended to receive chronometer revolving gears system trunnion. Resilient structure and central section are formed by solid part (6), formed by monocrystalline quartz, and blind hole has, at least partially, shape of truncated or non-truncated triangular pyramid, whereon trunnion end thrusts butt-to-butt. Invention also relates to similar type impact resistant bearing production method, wherein solid plate is processed in monocrystalline quartz anisotropic etching bath.
EFFECT: preferably on two sides of plates two corresponding masks (20, 26) are placed for simultaneous quartz etching on both sides.
