I would not be concerned about the movements in dress watches being used as every day watches. In the past, many people only owned one watch and wore them every day. When we look at them today, we consider them dress watches.
I wear jeans and a polo shirt 90% of the time when I leave the house (with a change to a dress shirt or sweater when the weather gets colder). Most of my watches would be considered dress watches (precious metal cases and leather straps) and I make sure to wear them all (otherwise, why would I have them? ), but I must admit I wear a stainless steel Overseas most of the time.
This is because I am more concerned about my knack of bumping into things and scratches in a stainless steel case worry me less than precious metal cases. I have one OS on a leather strap and one on a SS bracelet. I also tend to wear metal bracelets more in the summer because I sweat alot and live in high humidity locales. (Being in Atlanta, I'm sure you can relate).
But I never worried about whether the movement itself would be an issue in any of my dress watches, which are almost all vintage pieces, as a daily watch...as long as I'm not excercising or doing a lot of manual work. I have a Casio Pathfinder for those occasions.
BTW, the classic cal. 1120 is used by VC in many of its ultra-thin dress watches and also used in the Ref. 222 luxury sports watch (as well as AP's original Royal Oak and PP's original Nautilus).
