Hey, hello! Good to "see" you.
OK, your questions: advantage of column wheel -- pulling power at the bar, assuming your pull target is a chronograph nerd at a watch convention in Switzerland. Eyes glazed over if not. To the manufacturer more cost unless you have cheap labour (eg Seagull) or high retail prices (eg Omega).
Hacking -- nothing to do with computers or horses. When you pull out the crown (that's the winder to most outside this knowledgable forum) the second hand stops. In theory this makes it easier to set the time to the second on your watch. Completely negated by the time it takes for the seconds hand to start up again after pressing in the crown which varies from 1 sec to 15 sec on my watches. And then, being a mechanical watch, it's 5 to 25 seconds slow or fast by the next morning anyway. If you want to know the exact time go to
https://time.gov/ or buy a $20 Casio.
Now, what you were not told when you paid your EZ-signup fee of $0.99 is that we are all crazy here. And the fee goes up by $20.00 pcm for every post where you don't include a picture of some sort.
Do not think we are joking, we have enforcement.....
