A horological dynasty is responsible, the Bronnikov family from Vjatka, Russia. The earliest model appearing in 1837 and rumored to have been purchased by the future Czar, Alexander II. A tradition carried out through the 1800s into the early 20th century by Semyon's sons Mikhail and Nicolai - Producing only one watch per month with approximately 500 ever made, and of those only about 250 have survived today.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
