Shinola's been around only a few years - I don't own one but like the styles - I did notice Costco in California just started carrying them in the last month or so - that speaks to Shinola's ability to handle both volume and returns - doubt it'll be collectible - if you have to, there's always ebay - turn the watch into cigars!
Sorry about the family feud - life is way to short - maybe a vintage cigar with your brother in law - Good luck!
