Left- I have the strong personal opinion that date wheels are even more of an obsolete complication than the mechanical watch itself is an obsolete tool. They break up symmetry of the face numerals/indices and gets in the way of the beautiful patterns or finishes. A tourbillon is useless, but at least it looks cool, is a complicated complication and exists because some one just felt like it.
