What was the wrist device before the pocket watch? A wrist-slide-rule?

  No. The pocket watch predates the slide rule (~1530 vs ~1630; http://en.m.wikipedia.org/wiki/History_of_watches http://en.m.wikipedia.org/wiki/History_of_watches, http://en.m.wikipedia.org/wiki/Slide_rule#History http://en.m.wikipedia.org/wiki/Slide_rule#History)
