The only issue is that nrf52 device without bluetooth is not that much useful, but it can still be used as ordinary watch. It could even work with Espruino IDE and apploader over the charging cable + some dongle if the stuff discussed here https://forum.espruino.com/conversations/380926/ is done. I still plan to look into it eventually.
