I had something similar happen a few weeks ago with the screen blank and the watch completely unresponsive. I guessed that it might be in some sort of uninterruptible loop as the watch seemed to be discharging quickly. The screen was blank and no bluetooth connection so I estimated this by measuring the charge current after leaving the watch for a bit. I fixed it by opening up the watch and shorting out the battery to force a reset. After doing this, I reconnected the charging cable to reset the battery protection circuit. A safer way would be simply to wait for a long time and then reconnect the charger:).
