I do like vintage mechanical watches and early electrics. Partly from nostalgia and partly because of their aesthetics and build quality. And, you don't have to spend anywhere near the cost of these "Leica" branded watches.
Many fine old watches can be had for well under $100 and they were actually made by the company whose name appears on them. I especially like the old American and American/Swiss watches popular in my youth like Hamilton, Gruen, Bulova, Elgin, Waltham, etc. Of course, these companies are now long gone and their names live on only as brands owned by others.
