$27 PineTime smartwatch that runs open-source software | Jun 2023
The PineTime is a great smartwatch if your main use cases are checking the time and displaying new notifications from your phone. The build quality is great and the hardware is very similar to the original Fitbit Versa. Battery life varies with use and I get about 5-7 days on a charge.

The most well-maintained OS for the PineTime is InfiniTime:

I'm not aware of any major brands that offer account free service. The problem is that a smart device like this is not worth much without some kind of app ecosystem, app stores generally demand accounts, and browsing app stores from a watch is not exactly ideal.

As far as I know, Tizen smart watches can function well on their own after setting up the account once and I believe cloud synchronization is even optional. However, Tizen for smart watches is a dead end, with Samsung getting back to Android Wearable.

There's PineTime (https://www.pine64.org/pinetime/), which is very barebones but open source. Popular firmware, such as InfiniTime (https://github.com/InfiniTimeOrg/InfiniTime) can also be flashed onto several smart watches available on your favourite Chinese import stores (for example: https://github.com/StarGate01/p8b-infinitime for the Colmi P8).

The pinetime can basically do anything you want it to, as long as you're willing to make it so. I'm wearing it on my wrist right now, but I have an iPhone and the support for it is not great. In terms of build quality, it's quite good, and the battery lasts for about a week. It's slimmer than an apple watch, which is a major plus for me. But if you have an iphone, step tracking and limited music control is all you'll get in terms of accessory use. You can always contribute, however, and there is a very active community working on the firmware in the github repo (https://github.com/InfiniTimeOrg/InfiniTime).

The thing that the PineTime does really well, however, is beat the price tag of basically every other smartwatch out there ($30). I'm not sure how chip-shortage prices might be affecting this though...
