The 15th edition, often sought in PDF format, represents the most comprehensive version of this classic text, spanning over 800 pages of technical theory and practical application.
Modern timing machines (Witschi, Timegrapher) give you numbers. Volume 15 gives you feeling . It contains a table of acceptable beat error variations when the watch is in pendant up, pendant down, crown left, crown right, and dial up. Unlike modern ETA specs which expect quartz-like precision, this manual teaches you how to adjust the mass balance of the screws to average out positional errors.
The first 200 pages are a masterclass in applied mechanics. It explains the geometry of the involute gear tooth, the physics of the balance spring (isochronism), and the chemical composition of ebauches (raw movements). It assumes you know calculus.

: This section covers the history of horology and the fundamental mechanical laws that govern timekeeping.
If you manage to secure a verifiable copy, here is how professional watchmakers utilize its teachings in a modern workshop. The 15th edition, often sought in PDF format,
Hans Jendritzki's Manuale Svizzero Dell Orologiaio Riparatore (The Swiss Watchmaker's Repair Manual) is a foundational text in horology, lauded for its 553 original illustrations and a comprehensive 101-reason troubleshooting guide. Spanning foundational theory to practical techniques, this 1948 manual remains highly relevant for modern watchmakers and hobbyists. Explore the publication details at Editions Simonin .

It is crucial to note that the Manuale Svizzero Dell Orologiaio Riparatore remains intellectual property of the Swiss training bodies (now part of Wostep or the FH). While out-of-print and abandoned, the PDFs exist in a legal gray zone.
The ".pdf" suffix indicates a scanned reproduction. The original paper versions were destroyed in many schools during the 1980s quartz crisis, making surviving digital copies the primary means of access today.
The (Swiss Watchmaker’s Repair Manual) is widely considered the "bible" of horological maintenance. Originally authored by Hans Jendritzki and published in 1948, it has evolved through fifteen editions to become an indispensable technical resource for both professional watchmakers and dedicated hobbyists.
It refers to the 15th revised edition . This is the "goldilocks" edition—not too old to miss the invention of the modern shock protection (Incabloc), and not too new to discuss quartz (which purists ignore). Edition 15 captures the peak of mechanical perfection : the era of the manual-wind calibers 1000, 1010, and the first automatic rotors.
