Watertightness - Screw down crowns
Does anyone else have OCD moments when screwing down their crown? I am always worried that I've not screwed it down tight enough to achieve full watertightness, but at the same time never want to overtighten..
IS crown tightness important for achieving waterproofing?
Wouldn't it be nice to have an indicator confirming adequate torque has been achieved.
Anyone got any tips to ensure it's tight enough but not over tight?

My understanding is that the seals are what makes the watch watertight, not the screw-down crown itself. The crown just needs to be secured sot hat it doesn't open accidentally. You shouldn't need to tighten the crown more than just to the point it stops turning.
I'm sure some watches have different systems, but that's my understanding in a general sense.
My only concern when screwing the crown in that I don't cross thread it

You are right, it's the seal(s) against the crown tube that matter.
It isn't that critical, just screw to the point where it's unlikely to come loose by itself. More torque doesn't mean more water proof.
