The top 2 are quartz, the bottom 2 are auto. It's so hard to choose which to wear each day.
And if you really want to muck things up . . . add a manual wind to the mix.
Bet you were expecting something else from the title.
EDITing to add something I posted a bit further down - The title is obviously click bait but the point of the thread is there is a place for both quartz and auto in a collection.
