Breaking the Stem... How Much Force Does It Take?

Busting Watch Myths - Episode 1 TEST WATCH: @ELYSEEWatches Ocean Pro MOVEMENT: Seiko NH35 Does setting your watch on your wrist damage the crown stem? To find out, I built a test rig and loaded the stem in the worst-case position. Result: The stem survived up to 1291 g (2.84 lbs) of side load before breaking. That's far more force than most people could ever apply with their fingers while setting the time. So while it's still not a great habit... you're probably not going to break a healthy stem this way. #watchmaking #watchrepair #horology #mechanicalwatch #watches
