It’s fine, people don’t fall into the sea and get saved by their watch very frequently.
I mean if you wanted one more reason to get back into wearing watches, sure, whatever works.
I vaguely Romberg those watches & that era. I didn’t have one, but I had some unreasonably complex Casio databank calculator. I eventually turned it into a fuel log for my first car, I think the calculator may have cost about 5% of the car’s purchase price (and the calculator worked, I had to sink more money into the car to get it to pass MD safety tests….they are picky in MD, like to the point where they insist the breaks actually stop the car and stuff…)
