There is a lot of literature on the Internet describing the history and development of the Bulova Accutron, the first tuning fork watch, so I’m not going to repeat it on this site. But as a very brief introduction, the tuning fork watch is like no other battery driven watch, or mechanical for that matter: it is driven by a tuning fork vibrating at 300-720 times a second, depending on the model; as a result, it doesn’t tick, but hummms. The index mechanism also means the tuning fork watches are characterised by a constant sweeping seconds hand.

With the lilt of Irish laughter

Every day and in every way

Now forever and ever after."
