broken crowns stems and tubes

[egroegart]

I've been seeing a lot of posts on broken stems, crowns and tubes. Lately I've been watching alot of youtube videos on info about rolexes. On every single video I've watched the people are way too rough with the crown, and every single one of them winds the watch seemingly as fast as they possibly can. I am just guessing but could this be a factor in why so many people are having broken stems and tubes? It seems logical. I also remember quite awhile ago a friend was winding his watch and did the same exact thing. When I wind my watches I do it very carefully. These are tiny parts, and replicas at that. i wouldn't wind a gen like all of these people are.

Ok, that's my rant for today. Anybody think this is a possibility why they are breaking?

On a serious note, yes, I agree OP.

yep,

i've broken the stem on my v3.5 by winding it too fast and rough

You should not see a broken stem,,,, they are the hardest part of a watch and shouldn't break unless they're not tempered properly which I have seen only in one specific model of replica movement. A very rare thing.

I'm mighty glad scientists are getting round to stem cell research. It's time this problem was resolved.:hehehe:

@Mitch. It's because stems are tempered that they break. When you increase the hardness of steel, it becomes more brittle. Un-tempered steel bends instead of snapping, but if the working end of a stem was too malleable, it would pretty soon get out of shape.:thumbsup:

They should be hardened and then tempered to reduce the chance of this happening.

Yup. My bad, confusing hardening with tempering. All I meant to say, anyway, is that hardened steel is more brittle.

 

[egroegart]

Hardened, temered or not, it is a tiny tiny piece that a person can easily break if mishandled.............I believe. :thinking:

 

[mitchbaria]

No they shouldnt break. It is not common.

Your right about this but stems are hardened as Bonesey pointed out and they should not break easily. They are the hardest part of a watch and it should be very hard to break them and definitely not under normal use, even rough use.

Ok, thank you mitch

Your welcome , you shouldn't ever consider this while handling your watch, however a major concern that is stem related for every rep owner is the proper way to engage the stem without dislodging the little clutch which is a major issue and one that happens very often. I don't know the correct term for this but just a word of warning about removing stems, it is very easy to take one out but can be very tricky to get it back in without causing damage to your movement so think twice before pulling a stem.

Check to see if the movement is aligned with the hole in the tube . If the movement is too high , too low or off center it can place lateral loads on the stem that can snap the stem.
