the bottom slots for 6 watches are very very thin. you cannot fit 6 40mm+ watches side by side without bumping/scratching. also, for the winding slots, there is very little gap between the two watches. again, with 40mm+ watches, you will have the crown touching the other watch which can potentially cause scratches. I hope it is sturdy.
cannot realistically fit all 10 watches
