You bought a timegrapher to understand your watches. Then you saw three numbers and a row of dots, and nobody told you what any of it means.

This guide does. It is written in plain English for hobbyists, not watchmakers.

WHAT YOU GET

• A traffic-light translator: every number on your screen turned into green, amber or red, with what it means in real life. “Plus 15 seconds a day” becomes “off by under two minutes a week.”
• An 11-pattern trace atlas: every common shape your dots can make, each with a picture, a plain explanation, and a diagram showing which part of the watch it points to.
• A worked example for every pattern, reasoned through step by step.
• A settings check that stops you panicking over a wrong setting instead of a real fault.
• The magnetism check: a common, cheap cause of a watch suddenly racing, and the quick fix with a demagnetiser.
• “Tell your watchmaker” lines: when a fault isn’t a do-it-yourself job, the exact sentence to say at the shop, so you walk in informed and don’t pay for work the watch doesn’t need.
• A printable one-page cheat sheet to keep next to your timegrapher.

WHO IT’S FOR: anyone who owns a timegrapher and wants to know what it’s telling them. No watchmaking background needed.

WHO IT’S NOT FOR: professional watchmakers. You already know all of this.

Built from the manufacturer’s own training material on how timing machines read a watch, with every source listed at the back. Delivered as a 21-page PDF download.
