Watch arrived, just opened. Am I the only one missing the separate instruction book on how to utilize the slide rule? I found descriptions of how this watch is boxed and it was supposed to ship with 1.General instruction manual (check). 2.Warranty card (check) 3.Separate Slide Rule (computer) manual (uh. . .NOT checked). . . . Does anyone know how to get the manual? I've not found online version. Thanks.
