I've just restrapped my Buren Intramatic with a nice tan leather strap. 1950's model, slim thin casing, black dial. Buren invented the automatic winding mechanism and were bought out by Hamilton, I think. A nice, understated watch versus modern big cased ones. Keeps good time and a clear easy to read dial/hands. A lottery win and it would probably be an Omega Moonwatch. Omega won the deal for the Apollo astronauts as it tested better than the alternatives. Hence the Moonwatch model. I believe the astronauts were presented with limited edition cars too. Corvettes.
