You don't need to keep more than 1-2 watches on the winder at a time, and maybe keep an open spot for your current watch rotation at night if you don't like to sleep with it on.
I used to keep 17 watches in winders running all the time, and then I figured out that was just plain silly! For the past few years I just keep a couple out that are in my rotation for the week, in one of my Wolf dual-watch winders or on my wrist.
The rest are stored in nice watch boxes inside the safe. I have many of my watches organized into two nice quality 10-watch glass-lidded cases. Although most of the Omega watches in the safe are now in those small red Omega service case (like a sunglass case with zipper). I put a sticky note on each case with which watch it contains.
Others like my Rolex are stored in a nice 6-watch case. Some others, like my Tudor GMT, DOXA Poseidon, or Grand Seiko are in those little clamshell zipper watch-cases that you can buy on Amazon. My Seiko Turtles are in a 4-watch Pelican case from Case Club, but I plan to move the Rolex into the Pelican if I pick up a 4th one (Deep Blue).
Outside of the safe are also my solar watches, in a pair of nice quality 6-watch glass-lid boxes near the window. My three 1-watch Wolf are empty, as is my nice 2-watch Eilux winder, but I'll save them in the event one of my favorite winders should die. But my inexpensive 2-watch Egard winder and my three 2-watch Amazon winders will go to my brother and my son when they need one.
Here is a picture from yesterday of one of the 10-watch boxes (not sure exactly where they came from). Before I ended up with over a dozen red Omega service cases I had my Omega's in this box, and it all fits nicely in my large safe.
Below is a picture from 3 years ago, so things have changed a bit. The quality brown wooden box in the middle of the picture is very similar to the two 6-watch glass lid boxes that now hold my solar watches.
Found an old picture of my silly winder setup, before I emptied them out to keep them in the safe. Two Wolf dual winders on top, and three single watch Wolf winders in the middle. Bottom right is a nice Eilux dual watch winder. The rest are cheap ones.
