Not weak at all. You'd need a lot of force to break something intentionally.

actually it was just a theoretical question(thanks God )i know the force train the set lever push the clutch lever to the intermediate wheel so i can imagine the quantity of force just wondering what sets the stem finally free :-)

I've seen various things happen.

1. Set lever gives way and slides up allowing stem to be removed. But with some level of marring on both the lever and stem.

2. Set lever breaks. Pretty self-explanatory

3. Portion of Stem against the set lever breaks.

4. Depending on condition of crown and/or stem threads , the crown may break off, come apart, or some combination of it.

Another thing to note, some models have a screw in the detent instead of it all being one piece. Best case scenario is this screw backed out.

i c , i guess my assumption was wrong that the force push the set lever to the clutch lever is high enough to cause damage on the intermediate wheel or further.

In my experience I've never seen that happen. But, I won't rule it out. Never assume anything. lol. I see something new almost everyday.

from engineering view it would make sense -making the set lever weaker than other parts- to prevent bigger damage ,in cycling there s a weak link between the frame and the rear derailleur , called RD hanger ,
hangers are meant to break away first in a crash / mis shift etc.
To break first, they are made to be the "weakest link"
I guess the second thing to break is the derailleur, third the frame yikes.

Does the 17013 oyster-quartz have the same keyless system? Mine did that, I managed to get it back in but it's tricky getting the movement to stop and start to sync the time or change the date. It's been happily ticking away in the box untouched since ~12/2015, waiting for the battery to go dead before taking it for a service lol.

Weel , a friend’s 1680 experienced the same issue, ie. Stem come out completely with crown intact when he tried to adjust the time.

Took me about 3 and a half minutes to remove bracelet, backcase, tighten retainer screw and pop the backcase and bracelet back on.

It’s likely that the screw would loosen again over time. And then its another 3.5 mins of my life gone with the wind ��

Never experienced it on my own RedSub though.

Old Rolexes are true workhorses and thats why i stick to them till today.
Dont fret when something goes wrong, its almost always simpler then you think.

Cheers
