Initially, I looked for an open source smartwatch that is sold with an opensource OS preinstalled. However, this was not really feasible.
- PineTime had some really bad first hand reviews in addition to them being quite expensive in the EU.
- Pebbles warranty is too low and it is rather expensive.
So as a second attempt I looked for operating systems that you can flash onto watches. I found Open-SmartWatch with OSW-OS and AsteroidOS. While I think that building your smart watch from scratch is cool, AsteroidOS looked more accessible and mature (just based on easy navigation and the feature list).
Sadly, the most supported watch is no longer available: TicWatch Pro 2018
So I thought I just mindlessly ask whether you have a different OS you would recommend or if you have a watch recommendation that is still available.
Used Pebble is one option.
If you can handle soldering in a battery, you can usually buy a Pebble or Pebble Steel for really cheap (just make sure it isn’t a first batch glued shut model). Don’t get a Round, batteries are really hard to find. Pebble 2 and Pebble 2 Duo will also need replacement side buttons, they disintegrate quickly.
Obviously they will have zero days of warranty though :p
