You're wearing your favorite watch....it's got a 2824-2 powerplant, 300m. WR rating, Sapphire Crystal...you lunge forward going for the ball and slip and hit the ground hard....the sapphire withstands the impact...the sweeping hand skips, jumps...then, the watch stops.
I'm one of the guilty parties....oftentimes, I overlook the shock-resistance feature, esp. when buying a mechanical/automatic watch. Presumably most mid-to-high end automatics have some sort of shock proof system like the INCABLOC or PANASHOCK. With the exception of Casio G-Shocks and other sportswatches, I'm guessing that most other lower-end or entry level watches will not have the "Shock-Resistance".
Is this a feature that is often overlooked......or we forget to include it on our checklist b/c most of us are too absorbed with features like ==> type of movement Swiss ETA 2824/Miyota 8215/Vostok 2416, etc, water resistance ISO rating, sapphire crystal, SS case design, among others.
"How Shock-Proof System Works" -- Acknowledgment: From Richard Paige Open Forum 2/8/98 TimeZone
Wristwatches by nature of their position on the arm, have always been problematic for damage. I'm sure most of you at one time or another have dropped or banged your watch into a desk, door, wall, etc.
By the 1930's the Swiss watch industry was coping with the demands of a growing audience for more "sport style" watches...those that could take more of a stressful existence. The result was several "shock" absorbing systems.
The most sensitive part of the watch is the balance assembly, this was where the innovators needed to look to solve the problem. As the watch took a shock..the balance wheel pivot had a tendency to "bounce" in the opposite direction of the impact...this sent the pivot up into the jewel and the cap jewel...often times cracking the jewel or actually breaking off the tip of the balance pivot...rendering the watch useless for timekeeping.
With the advent of the "shock-proof system"...the impact was absorbed. This was accomplished by placing a metal spring system over the balance jewels..this allowed the pivot and jewel to rise away from the balance plate thus absorbing the shock, and then to return back down to it's original position.
In the picture, the jewel is in red, the cap jewel in pink...the pivot is in green, and the "incabloc" shock absorber is in yellow.
