More like "quartz movements are the equivalent of a stainless steel knife"
I have 4 mechanical watches, and the quartz Sinn UX. The UX is my everyday watch to wear for work, where I may be climbing around buildings, etc., and not just sitting at a desk. It has a date wheel, and I don't need to worry about futzing around resetting the date every Monday because I did not wind it over the weekend, etc. It also keeps much better time, which is important to me for work, especially if I have meetings, telecons, etc. I have the mechanical watches because I think they are cool, and not because they keep better time (they don't -- not even close). They do not do anything better than the quartz, plus they are all more easily scratched, etc.
My main issue right now is that I like the UX so much I have yet to wear the 2 recent mechanical watch aquisitions except around the house.
