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