There are only a few features I care about in a smartwatch:
1. O2 monitoring. I have sleep apnea and live at high altitude, so this matters to me.
2. Motion sensor. Also mostly for tracking sleep.
3. Vibrator for notifications.
4. A screen backlight.
5. Battery life longer than a week.
6. Waterproof enough to survive a splash in the shower/rain.
I consider GPS, cellular, AI, touchscreens, cloud-only sync and control apps, and just about everything else to be anti-features. There are no devices that really cover all this that I've found. A few Garmin and Amazfit/Zepp devices come close, but they have enough drawbacks for me to not be happy with them. The new Pebble is nearly perfect, but the lack of an O2 sensor is a dealbreaker for me :(
- Findecanor 6mo agoThe Sensor Watch circuit board [1] inside the case of a Casio F91-W / A158W / A159W satisfies 2, 4, 5, and 6. Accelerometer or thermometer available as daughterboard. Battery life measured in months, if not years. Although the simple LED backlight and the segmented LCD leaves a bit to be desired, and there is no wireless connectivity for notifications. Open source firmware. The Ollee watch circuit board [2] is similar, better backlight but closed-source firmware and configuration over BLE in a smartphone app. Still no notifications over BLE though. I'd think combining 1 and 6 (O₂ monitoring and waterproofing) would be difficult.

- curiousgal 6mo agoThe Pro version has a better screen (still segmented but more), RGB LEDs and an infrared sensor.
- doctorpangloss 6mo agomy experience with a sensor watch has been terrible. imagine breaking a $3 watch that is not quite as indestructible as people think it is, but it is nonetheless pretty robust, and then trying to shove something 100x glitchier and 5x as expensive into its case...
- zimpenfish 6mo ago> I'd think combining 1 and 6 (O₂ monitoring and waterproofing) would be difficult. By O2 monitoring, they mean "blood oxygen through skin via LEDs" - there's no impact on waterproofing from that (as the Apple Watch demonstrates.)

- permutations 6mo agoWell as a pebble evangelist I have great news! The heartrate sensor on the PT2 can also do O2 monitoring, they’re planning on implementing it in the future :)
- MrDrMcCoy 6mo agoThat is excellent news! Looking forward to that :)
