There is no need to unscrew the crown, just give the watch a few shakes. There is also no harm in unscrewing the crown over and over; the twinlock is very well engineered, precisely machined, and very durable. I do keep my automatics on a winder, but that's mostly because not all of mine have an easy date adjustment. That does look like a nice winder. I have Pangaeas (I'm using a four winder, at the moment, but I have others), which are well built, nearly silent, have excellent settings adjustment and look fine, but they don't look as nice as that one.
