Vintage antique Star Watch Case Company Nickel Swing Out Pocket Watch Case with crystal, missing crown. Hinged inside.  Hinge works great.  Some wear and scuffs on case but should polish up fine, all i did was clean the dust off it.  Found in basement of my dads long closed family jewelry shop.  Outside case diameter 2 1/4” so a pretty large case! Inside diameter for movement looks like about 1 3/4"
