I think there is some pretty innovative stuff coming out of Japan right now. The high accuracy quartz models from Seiko (under the Grand Seiko brand) and Citizen have insane accuracy measured in seconds per year.
Of course if you want to limit the discussion to the mechanical realm the Spring Drive is for all intents and purposes a mechanical watch with an electromagnetic quartz feedback loop slowing the unwinding to the correct pace to keep time. Not as accurate as the full quartz but very impressive and it truly glides (instead of ticking).
