Thanks!
I just found the watch amongst! Even outside of DFU mode it advertises "00001530-1212-efde-1523-785feabcd123" which I'm pretty sure is the old DFU as the new one seems to have 16 bit UUIDs?
Maybe the firmware updater downloads the file then? I'm pretty convinced it is NRF52 - it says nRF52 everywhere I look and surely you'd have to be a bit crazy to add GPS to an NRF51? I took the watch to bits a while ago and sadly I can't read the chip number because it's scribbled over, but nothing I can see points to it not being an nRF52.
