       | Recommend the title be changed to "Casio F91 smart watch reboot".
       | It's kind of nonsensical as-is.

       | I love my F91 (I'm wearing it right now!), and I love minimalist
       | smartwatches. So this is right up my alley. I hope it keeps
       | moving forward!

         | This is not moving forward, it looks like the author is just
         | lofting it up as a resource for others to use as a starting
         | point for similar projects.

           | Deeply heartfelt thanks to the original author for taking it
           | this far.

       | Wow. There is another project doing a similar thing, but they
       | don't have bluetooth nor an OLED display (they reuse the same
       | display) so it's not nearly as useful in daily life, though still
       | very impressive work nonetheless.
       | 
       | But this is really amazing work. I hope you find some
       | collaborators to continue!!
       | 
       | I recently got an F-105W which I had when I was a teen (which is
       | basically the F-91 but with a cool glowy EL backlight). And one
       | thing that really surprised me how small that thing is. It seemed
       | bigger at the time.
       | 
       | I'm really amazed how much technology this project managed to fit
       | in that tiny case. Battery, OLED, bluetooth.. Just wow.
       | 
       | I would pay for this, I was thinking of buying that other project
       | on crowdsupply but without BT connectivity I just don't really
       | have any use for it.

       | Very interesting. One thing I've pondered - this project contains
       | various pieces of off the shelf hardware, and some custom 3D CAD
       | files. These don't seem to fit as neatly into the way Git
       | functions. Is there/has there been any attempts to replicate Git
       | with Bill of Materials or 3D CAD data?

         | There are many softwares attempting to solve this problem.
         | Airplanes, bridges, cars, robots, they are catalogued in these
         | systems. They tend to fall under the "Product Lifecycle
         | Management" or 'PLM' name of softwares. Or also "Product Data
         | Management"/'PDM'. Tends to be enterprisey.

           | I've used those systems previously. Sadly, none seems to be
           | functional on a distributed scale like Git functions for
           | codebases.

             | Ah, I misread the framing of your question. We are in the
             | same boat, I have had the misfortune of using those systems
             | as well.

       | Very cool. I'd prefer Sharp's memory display which uses power
       | like ePaper display, but looks and works exactly like a
       | traditional LCD with high refresh rates. And bluetooth/etc is not
       | a feature, but a bug IMO; goes against the philosophy of F91.

         | 
         | Forcing all setup to go through the needle's eye of a couple of
         | buttons is profoundly limiting, and a wired connection would
         | violate F91 design esthetic more.
         | 
         | A transparent back for the watch, and optical components, could
         | open biomedical opportunities. There, Bluetooth readout of
         | logged data would be useful.
