A method of shock protection for a wristwatch movement, developed in the 1930's. Other named techniques for shock protection include Parachoc, Kif, Unisafe and Novochoc. Incabloc prevents shock damage by allowing the jeweled balance of the watch to move laterally and vertically within a spring-mounted setting. Incabloc is used by many movements including most modern ETA and Omega movements. See also 'Kif' below.
