The watch; its construction, its merits and defects, how to choose it, and how to use it
A practical handbook on watch construction, repair, and selection written by watchmaker Henry F. Piaget and printed for the author in New York in 1860, aimed at owners and buyers as much as trade horologists. The relief-cut diagrams show balance wheels, escapements, gear trains, and loose plates and screws in flat black outline with hatched shading, usable as mechanical motifs or spot ornament.
