Someone over on the Cruisers Forum mentioned a crowdfunded project called Sensor Watch to upgrade a Casio F-91W. I skimmed the page and found that the makers claim that:

"Sensor Watch is a modern hardware drop-in for the classic Casio watch. It takes an iconic 30-year-old design from a golden age of digital watches, and pairs it with a modern, powerful microcontroller. This small circuit board, less than an inch in diameter, replaces the original quartz movement in a Casio F-91W or A158W watch to put the capabilities of an ultra-low-power ARM Cortex M0+ microcontroller on your wrist."

and:

" With fine tuning, Sensor Watch Pro can drift less than a second per year."

and:

"It also looks hella cool."

They are also offering an accelerometer that can be added to the watch to bring it out of "low energy mode" (whatever that is), and a new LCD display which "offers a decimal point and a leading 1, for displaying longitudes and temperatures above 100 degrees." Apparently, the watch can display the time of sunrise and sunset (I presume that's what the longitude display is for), the Moon phase and world time, among ... other things.

You can pre-order one for $60, which sounds reasonable to me if all of the claims are true and the watch functions reliably. However, part of me wonders why they didn't just make a whole new watch. Perhaps using an existing, proven case keeps cost down? IDK.

Anyway, ... what say you?

Cheers!
