====== Incabloc ======
**Incabloc** is a common [[shock protection]] system used in mechanical watches, recognizable due to its lyre-shaped spring.

===== History =====
Incabloc was developed and trademarked in [[1933]] by [[Portescap]]. It prevents a watch [[balance staff]] from breaking by allowing it to move slightly, both laterally and vertically, using a spring-mounted jewel setting. Incabloc is easy to recognize due to the golden shield- or lyre-shaped spring clip around a ruby at the top of the balance. This is hinged, allowing the shock absorber to be lifted in place so the cap stone and the rest of the anti-shock pivot can be removed.

Incabloc was developed in [[1933]] and introduced in its current form in [[1938]]. It remains one of the most popular shock protection methods.

Incabloc is also the name of the company that produces these shock absorption systems, a successor to [[Portescap]] which divested itself of Incabloc assets between [[1988]] and [[2003]].

Incabloc makes both removable and hinged anti-shock mechanisms
