As I understand it, what you see over Bluetooth is completely configurable so just because it reports itself as Nordic doesn't mean it actually is - but it's a very good start, especially as that link you posted mentions nRF52832 explicitly.
Do you have a link to the latest firmware? I've love to find one of these watches that comes with an unlocked bootloader, as cracking them open to flash them is a pain - it requires extra hardware, fine soldering, and there's a reasonable risk of breakage.
