About This Book
The book presents practical rules and procedures for adjusting and regulating precision watches, beginning with temperature compensation and the design and adjustment of compensation balances and springs. It describes required equipment and contrasting commercial and observatory rating methods, then treats isochronism, hairspring pinning, regulator pin manipulation, and positional timing with step-by-step diagnostics. Numerous worked examples illustrate three- and five-position adjusting and the labor involved. Final chapters cover timing, poising and truing balances and hairsprings, cleaning essentials, and other shop techniques aimed at restoring accurate rate under varied conditions.
