Movement — Watch Repair

Movement teaches you to build and repair watches — properly, from the ground up. Start by changing a strap. Finish by stripping, cleaning, oiling and regulating a mechanical movement. Every step is explained in plain language, with illustrations and interactive diagrams instead of walls of text. WHAT'S INSIDE • 83 lessons across 11 tracks, from everyday care to full servicing • A guided "First Project" path if you don't know where to begin • Interactive diagrams you can explore — watch the escapement tick, toggle the keyless works between winding and setting, run a chronograph's start, stop and reset • 17 illustrated plates with tappable labels on every part • Complete service walkthroughs for three real calibres: the ETA/Unitas 6497, the Seiko NH35 and the ETA 2824-2 • Guides to 15 movements you'll actually meet, with specs, common faults and service notes LEARN BY DOING • Diagnostic decision trees — answer a few questions and get to the likely cause, then straight to the fix • Quizzes on every track, plus a "review weak spots" mode that revisits what you got wrong • A private practice log for the watches you work on: notes, tags, photos, and a service history BENCH TOOLS • Calculators for daily rate, beat rate, power reserve, amplitude and beat error, strap sizing and battery cross-reference • Printable cheat-sheets for the oiling chart, water resistance, battery codes and lug sizes • A glossary and in-depth reference guides BUILT FOR THE BENCH • Works completely offline — no account, no sign-up, no internet needed • Nothing is collected. Your progress and practice log never leave your device • Light and dark themes Whether you're curious about what's inside your watch, restoring something inherited, or building one from parts, Movement is the guide that stays open on the bench beside you.
