That scenario is less likely to occur in most developed countries. And if I loss power for few days, I think my concern is air conditioning, heat, refrigerator, hot water, washer and dryer first.What happens to your computer peripherals if they go without power for a few days? For a mechanical watch, that's no problem.
But forget about the practicality for a moment, you are talking about some cheap electronic watch that is disposable after 2/3 years vs. a mechanical precision timepiece with a complex movement making it timeless (no pun intended). This is apples vs. oranges.
