Precision Engineering AG Introduces Their First Cylindrical Hairspring

Unless you’ve started your journey down the rabbit hole of obscure watchmaking technologies, including but not limited to hairspring manufacture, you probably haven’t heard much of Precision Engineering AG and the very few companies like it, capable of producing the smallest, yet vitally important components in mechanical watchmaking. Precision Engineering AG (or PEAG for short) is an independent subsidiary of the Moser Watch Holding group, and produces escapement components for sister brands H. Moser & Cie. and Hautlence, in addition to high-profile third party clients who reserve their rights for anonymity. The latest creation to emerge from PEAG was unveiled at the 2018 EPHJ show in Geneva; a cylindrical hairspring, which is in fact not a new invention at all, but one that remains extremely difficult to produce.
