Why not a lillygo T-Watch? It's a bit more expensive, but it's a solid one with good specs and an esp32 https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library

What Hacker News says
6 sourcesHope it isn't similar flop as "Lilygo TTgo T-Watch" which it's barely usable but not due to meager hardware specs. It's the software with hardwired long boot sequence so you either live with the ESP draining battery out in few hours or waiting some second every time you wake the clock up. The manufacturer just assumed you want it to be always on and connected and counting steps and whatever, battery life be damned.
I would be fine if it wakes only once in 5 minutes to get online or on pushing the physical button. The hardware is there. But the manufacturer just don't care.

In An Open Source Mobile Phone Based on the ESP32I have this watch, and got it to tinker with since it had some fun sensors, mic, and speaker.
Haven't turned it on in a while, but the battery life was definitely measured in minutes. It will not last anywhere close to a full day, even with a bunch of optimizations and certain things turned off. Even with the display off, ESP32s drain tiny batteries.
It's only practical for tinkering, and an M5Stack is definitely a better choice for that.
EDIT: Checked my notes. I was able to get it past the 24 hour mark with some work.
This repo has some helpful info: https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/blob/m...
In Low-cost Smartwatch powered by ESP32 module- Banglejs has GPS but is big and has no established HR or step counting algorithms
- PineTime is more Apple-like, but the firmware is less mature and has no GPS
- TTGO T-Watch has no HR sensor AFAIK, but some versions may have GPS (see https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library)
- TTGO T-Wristband is like Miband but has no HR sensor again
Of course, you could buy an Android watch or an Apple watch and program your own apps.
In Watchy: Hackable $50 SmartwatchThere are several versions with confusing names. V3 has the microphone. I think V2 was never mass-produced. Differences can be found in this table, which also links to AliExpress item listings: https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library#-versi...
In Watchy: Hackable $50 SmartwatchSee also the TTGO T-Watch-2020 which is based on an ESP32 processor.
