My new #Casio #f91w is using a CR2016 battery, which holds 7 years.

There is an offer of 20 of them at Amazon for 6,79 EUR. This means for less than a Backfisch my watch can run 140 years… this is mind blowing. 🤯

Does anybody need to know the time? Let me check on this beautiful present of my wife 😍

Feels so light and small compared to my Apple Watch. Battery should hold for 6+ years. Amazing. And no notifications during my baby vacation.

A visual essay by Terry Godier.

CASIO F-91W
$12.
21 grams.
This watch has told time the same way since 1989.

It doesn't know my heart rate. It has no opinions about whether I've stood up enough today. It will never need a firmware update.

When the battery dies in seven years, I'll press in a new one with a paperclip. That will be the entirety of my obligation to it.

Fad, fashion or fantastic?

This post from @tg resonated with me profoundly particularly after my experience setting up a Pixel last week. That took hours and left me depleted and scornful instead of joyful & excited about a new device.

It's a beautiful post on a gorgeous blog too from the dev of Current RSS for iOS. (I sure hope Current comes out for Android one day.)

#Software devs could learn a thing or two about knowing when something is finished and leaving it alone. #Casio has that lesson in the #f91w
