Escapement Papers: a measured bench for watchmaking
A tightly structured publication about mechanical watch escapements, combining definitions, bench procedures, dated notes, and measured four-cell cards.
Field notes
The publication divides its material between mechanism definitions, bench procedures, and dated notes, with each area linked from the homepage. Its recurring card records rate in seconds per day, amplitude in degrees, beat error in milliseconds, and lift angle; the site treats that fourth field as the disclosure that makes the other readings interpretable. Issue 01 also includes instructions for six-position regulation and a camera-and-clock method for measuring rate without a timing machine.
