General Science / Re: If I wear ANY battery watch, within a week the battery is dead. Why?

If the cellphone charge duration is normal, then the problem lies with your wrist environment. Sweaty wrists, or failure to remove a cheap watch before washing the dishes, bathing the dog, working on a trawler, or scrubbing up, can corrode the battery contacts. Judging from your extensive career and life experience, I find it unlikely that your grandfather had many battery-operated watches as they did not exist before 1960.
In a spirit of scientific enquiry, you could invest in a solar-recharged watch. Accurist and Citizen make reasonably-priced "eco-drive" watches that are well sealed against the usual insults (mine regularly cycles up to 15,000 ft and I will admit to some sweaty moments) and never need to be opened - the one I am wearing now has run continuously for over 10 years. As a control, you could wear a self-winding mechanical watch on the other wrist, and see which one fails first.
