I suppose that each persons idea of what is viable is different. If you say bought a decent discontinued Rolex Sub for example (LV, 5513, 1680 ....) then you could probably expect a modest return and have the enjoyment of wearing it. If it just sat in the safe though, a modest return can probably be bettered; Stock Markets, Commercial Property etc, etc. Some people may also get pride of ownership by holding a watch in the safe but not wearing so again, for some this will make modest gains acceptable.
