As for the Pelican 1500 I picked
link it because I knew it would hold more than a dozen watches
link turns out well more it's watertight crushproof and dustproof has stainless hardware two lock points a
link fully sealed lid automatic pressure equalization and a mega warranty. The 1500WF the case shown in this report includes Pelican's "Pick N Pluck" foam which means the layout is easily entirely customizable.
