Yup. smartPwn is the ultimate pocketwatch.

For good or evil...
Extrapolating that, I got given a basic fruit watch by work.
<snip>
I've looked at the fruit-watch concept, and concluded that -- to me -- battery intervals less than 1 year are unacceptable, or at least very impractical.
My daily driver, presently, is a rather old Citizen Navihawk, given to me by my father. I've had it serviced and I'm quite happy with it.
I also have a Seiko SKX007 (automatic, diver's) on a NATO strap. It is in need of a new movement, I'm afraid. If my supply of round tuits gets enough of a refill, it'll get a visit to the watchmaker and goes back to being my 24/7 companion, with the Navihawk getting demoted to travel watch (it displays UTC and one or two other time zones simultaneously). The Seiko has enough glow-in-the-dark material that it actually works. And I can read it without glasses.
My wife got me a dress watch, a Holzkern made from wood, which I'm wearing on special occasions.
I have of course installed an RPN calculator app on it
I can say, from personal experience, that the DM42 beats every app.
(my phones and computers all have RPN calcs installed, of course.) I must confess to being raised on algebraic calculators,
and being a math illiterate, RPN is both confusing and unfamiliar, but I'm getting good results, and forcing myself to do more calculations with it.
