Couples therapy my man. Someone that is trans friendly. You’re both fighting depression and that’s valid but can ruin a relationship, believe me it ruined mine. At couples therapy we found that the issues that were forefront in our brain (ie, hair) weren’t the fundamental issues.
Look into Bangle.js, it’s what I have, it fits some, not all of your requirements.
It’s open source, both the hardware and the software so no lock ins whatsoever.
They advertise a 2 week battery, mine lasts closer to a month between charges.
You have to install any features you want (every feature is opt in, not opt out).
There’s no speaker, microphone, or keyboard though, so no calling or texting straight from the watch. It’s currently £77 before shipping.
