Firehouse Horology manufactures silicon components for the watchmaking industry, including hairsprings and escapements. The New York based company is one of a very small group worldwide manufacturing hairsprings, which are one of the most complex parts in a mechanical watch. The hairspring is responsible for the precision of a watch, including its stability over a range of temperatures. The novel silicon compounds invented by Firehouse Horology dramatically improve the durability and precision as compared to previous generation silicon hairsprings. The manufacturing of these hairsprings is not outsourced. The research, development, and production are all done by Firehouse Horology at Columbia University in New York City.
