I'm making an IR beam break timer to train my dogs in agility.

The device that sets up the WiFi network is shown above. Internal components are a ESP8266 D1 mini and a 4 digit, 7-segment display

and a WiFi beam break detector sends a UDP message to the controller/display when the IF beam is broken and restored. The controller/display and the beam break sector use the same ESP8266 D1 mini.

I noticed that some reprogrammable wristwatches used these same components I was using (including an SH11106 display controller and D1 mini and wearable version

Now I'd like to reprogram a watch to have the same functionality as my mockup so I'm looking for suggestions about which watch to convert.

I don't need any functionality that comes with the watch. I only need to support becoming a WiFi controller. It must support Arduino create/Editor. I only need a single button to support reset and an off/on button

I would like to know people's experience in reprogramming wrist watches

No customer reviews. I'll bet the battery life is poor.

A few years ago I bought one of the TI ez430 Chronos programmable wristwatches, which used a built-in radio for program upload. It was fun, but after about 3 uploads, the CR2032 battery was exhausted.

I actually own one of these LILYGO, it uses an ESP32 as opposed to a ESP8266 or a 8266 D1 Mini. Since those are all related products I was going to make it work for me, but when I looked at it, there were so many great apps on it, I didn’t want to waste it. I’m thinking a Dstike Deauther watch.
