Historical Mechanical Clock Diagram - Engineering Illustration #3763240 (License: Personal Use)

This black-and-white line illustration depicts a sophisticated mechanical clock or chronometer with five circular dials-likely indicating hours, minutes, seconds, and possibly astronomical or tidal data-mounted on a tiered base. A prominent vertical gear wheel with internal fan-like vanes suggests an escapement or regulator mechanism, connected via levers to the central dial assembly. The precision linework and technical layout indicate it was likely published in a scientific or engineering journal of the late 1800s.

Commonly used in educational articles about horology, antique timekeeping devices, or mechanical engineering history; serves users seeking visual references for historical clock mechanisms or illustrations for museum exhibits and academic papers.
