 2 popular types of shock protection - Inca and KIF. KIF is more popular nowadays. As Eric mentioned, it goes over the cap jewel on the balance staff.

Before the idea of shock protection, if you dropped a watch, the balance staff couldn't absorb the impact.

p = mv = F*delta(T) ; its a bitch.

OK. Can someone explain what makes a watch "shockproof." Is it the retainer ring? Are there little shock absorbers inside the watch? :D:D:D
