Thanks for cour comment. I'm using the wristwatch since more than half a year, and it's still the first battery in.

But I started thinking about a charger. An external modified TP4056 should work. Something like the $1 Coin Cell Charger. I just need to add a connector for charging.

A build-in charger would consume a lot of space.

I really like the look of these bubble displays and have been meaning to do a project with them. Your overall aesthetic on this one is quite pleasing... the bright blue body next to the copper clad is quite nice!

This would be great with a rechargeable coin cell and with the charger built-in.

  Are you sure? yes | no
