So we’ve kind of established that shocks are bad for your watch, right? Sorry if this seems like a stupidly obvious thing to say, like “don’t use your hairdryer in the shower” or “drinking on an empty stomach is only fun for about an hour” or “the girl who owns every single Celine Dion album ever recorded will be a disastrous addition to karaoke night”.
Common sense is far from ubiquitous, however, and you’ll still come across plenty of watch owners who commit acts of heinous atrocity upon their timepieces, like this one guy I heard about who took his Vallée de Joux grande complication off-piste skiing.
On the bright side, the vast majority of watches have some form of built-in shock protection via their sprung balance endstones. Also, because movement constructors are skilled professionals who know exactly what they’re doing and can probably call on the power of Grayskull if needed, a great deal of shock resistance is also integrated with the very architecture of the watch itself — the optimum placement of gears, angles of engagement, shape and thickness of plates and bridges, all that stuff.
As a result, your watch can actually take quite a bit of a beating. I’ve been to a few watch manufactures, and one thing they like to show us is the shock testing in the quality-control department. Basically they whack a watch with a mallet, and although I’m not much of a screamer (I care about maintaining my cool exterior), you can usually read the scream in my eyes when they do that.
