Ever wondered what the Bulova Accutron looks like slowed to 240fps?

Slow-mo is cool. There are no two ways about it especially when the subject is watches. I'm honestly surprised there aren't more videos of watch collectors out there using either specialised kit or more make-shift inventions to record escapements or second hands in slow motion. That being said Reddit user pinhead26 made use of his iPhone 6  by recording in great detail what the tuning fork movement of the Bulova Accutron looks like close up. The Bulova accutron was the world's first fully electronic watch which completely abandoned the electronic/mechanical combination that Hamilton had pioneered and instead used a tuning fork. The open dial of the Spaceview reveals the futuristic technology beneath and is a favorite among collectors so it's great to see one from such a unique perspective. 

Pinhead did say that the extreme "wobbles" of the two oscillators behind the second hand are Nyquist distortions (Don't worry I didn't know what that meant either) because of the difference between the movement frequency of 360hz, the sampling frequency of 240hz and the scan rate of the camera. So not as accurate a representation as one would like however the video still shows just how high beat the second hand is as even slowed down it still is as fluid as ever. I have to applaud him for the rather unique way in which he captured this footage; iPhone 6 through the magnifying glass of a Swiss Army Knife. Bring on the new wave of macro slow-mo watch shots!
