I recently got a Pelican 1400 case with 10 watch slots: https://nalpak.com/cases/nalpak-watch-cases/ The cores that fit inside your watch are of a realistic size and they smoosh down easily to get them in. The Pelican case as you may know is airtight and waterproof. A little spendy, but its precious cargo would be well protected! I am very happy with it.
