Ehh the F91W is not very accurate at all as the article claims. It's not temperature compensated. If you leave it lying on a desk at room temperature yes. Wear it outside in all weather it'll be pretty inaccurate. I prefer the F-105W myself. It's basically the same watch but with a great blue EL backlight.
How many seconds of time accuracy have you found that this watch loses over the course of its 7-year-long battery life? I think I can handle it losing 30 seconds of accuracy per year.
I know its a cheap watch but would it be that hard to have a settings for it? I hear people tuned antique pendulum clocks to seconds per year. I suppose it helps that they are inaccurate enough to have tuning?
