Does anyone know what NFC transponder they might be using? I might have filtered too much on Mouser and missed it, but I'm struggling to find an 8KB module with that case. I also can't find it on the site since there's no BOM.

Freeze the video at 1:47 and you'll see K352 4SDYU from STMicroelectronics. Dug a little and came up with M24SR16-YDW6T/2 which can be found in DigiKey here: https://www.digikey.com/products/en?keywords=M24SR16-YDW6T%2...

That one is only a 2Kb though. They also make an 8Kb 4SFYU: https://www.digikey.com/products/en?keywords=M24SR64-YDW6T%2...

I am pretty clueless when it comes to NFC, does adding such a chip mean i could copy my Mifare Classic card onto the watch? That would be neat!

Goodness, I'm blind, completely missed that shot. Thanks!
