Eight guides on measurement, maintenance and the culture of mechanical watches. From the COSC protocol to the piezo contact mic, from magnetization to service: everything WatchScope has to say, in a single index.
What the Contrôle Officiel Suisse des Chronomètres is, the seven test rules, the five canonical positions and how WatchScope verifies them.
Open the guide → Measurement · DiagnosticsRate, amplitude, beat error: what each parameter means, what healthy values look like, and when to start worrying.
Open the guide → Technique · ToolsQuiet environment, hardware calibration, external piezo mic: the three factors that take the smartphone to bench-grade precision.
Open the guide → Maintenance · DiagnosisWhen your watch suddenly starts running +40 s/d, try the 15-euro demagnetizer before booking a service. Cause, diagnosis and fix.
Open the guide → Culture · ISO 228103 ATM doesn't mean 30 metres of diving. What ATM/BAR/metres ratings actually mean and why a splash-resistant watch doesn't belong in the shower.
Open the guide → Technique · COSCCH, FH, 9H, 3H, 6H — why these five, what each one reveals about the movement, and how to run a complete session with WatchScope.
Open the guide → Maintenance · CostsReal-world intervals (not the 3–5-year marketing line), objective signals from WatchScope that flag an imminent service, typical costs by calibre tier.
Open the guide → Documentation · APPEverything WatchScope can do. From adding your first watch to predictive diagnostics, one screen at a time.
