Does anyone know why clocks and watches are almost always photographed with the hands placed at 10 and 2?
Yes. Though I can't remember the exact reason, it has to do with at least two things. First, most new watches come from the factory with the hands set at 12 which looks illogical in the photograph. The other has to do with potential ten past ten and ten minutes till two represent. There more productive time left in either the morning or the afternoon. Somewhere along the line it became stuck as the expected norm of an add watch.
