  • Wow! Look how fast that index wheel is turning! I really didn't expect it to go that fast! Those notches are amazingly tiny!

  • @ihatestupidsignups

    Yes, but the actual technology was developed at Bulova's Swiss headquarters in Biel, by a Swedish engineer named Max Hetzel.

  • @douro20 The original Accutrons were not swiss. US made.

  • The index wheel spins more than 38 millions times / year.

    When it finally dawned on me what's happening inside an Accutron, I completely shit a brick. Now I have a ton of them. GREAT WATCH!

  • Wow! Looks more like a record with tone arm(s) riding it than the pawls moving the wheel.

  • Awesome!

  • A marvel of modern Swiss engineering. To make this work required a level of precision never before seen in the watchmaking industry. If I remember right, each of the wheel teeth is smaller than the diameter of a human hair.

  • 360hz tuning fork frequency. Those pawls ratchet over a million times per hour. Mine has been doing that with minimal maintenance (cleaned about every decade)for forty years.

  • That is a pretty amazing view!! I own three of them. Super cool! THANKS

  • alright, that is how it works.

    what's the expected mttf for the accutron? is there a need for maintenance?
