Male link cicadas produce their song by vibrating special organs in their abdomens called tymbals, which are layered plates made of a springy, elastic protein link called resilin. The sound the tymbals make when they vibrate is amplified by the cicada's hollow abdomen, and can reach a volume of over 100 decibels – that's about as loud as movie theater loudspeakers and just a few decibels shy of a rock link concert.

I was so terrified of trying to figure out what all the three link subdials were and how they worked that I had the watch for a month or so before I got in touch with Mark Hackman who works in the Hodinkee Shop and has been link my "what is going on with link these here watches" buddy for more time than either of us would care to admit.
