Full description
WatchScope is the ultimate pocket-sized timegrapher for watchmaking enthusiasts, collectors and watchmakers. Replace bulky and expensive hardware machines with your smartphone: simply use the microphone to analyse the "beat" of your mechanical caliber with very high precision. Whether you're regulating a Seiko NH35 movement, calibrating a vintage watch or checking the performance of your luxury chronograph, WatchScope gives you all the technical data in real time. CORE FEATURES (FREE): • Daily Rate measurement: discover how many seconds per day (s/d) your watch gains or loses • Beat Error: detect asymmetries in the balance wheel's oscillation (in milliseconds) for perfect calibration • Amplitude: enter the correct Lift Angle and monitor the health of the mainspring barrel and mainspring • Automatic BPH detection: the algorithm recognises the most common frequencies (18,000, 21,600, 28,800, 36,000 VPH/BPH) or allows manual entry • Until 5 full COSC test per month: 5 positions, the same methodology used by Swiss chronometer certification institutes • Shareable public vitrine (watchscope.app/collection/your-username) • Cloud collection: save up to three watches in your digital archive and track performance over time PRO TOOLS: • Unlimited cloud collection: save your watches in your digital archive and track performance over time • Built-in caliber database: ETA 2824, Valjoux 7750, Lemania 1872, Sellita SW200, Miyota 9015, Seiko NH35 and hundreds more • Next-service prediction based on rate and amplitude trends • Detailed diagnostic PDF reports with charts and maintenance prediction • Device hardware calibration for sub-millisecond accuracy • Ad-free experience HOW DOES IT WORK? Place your smartphone's microphone near the watch case or crown in a quiet environment. Our algorithm filters background noise and isolates the ticking of the escapement, drawing scrolling rate and beat-error charts in real time just like professional timegraphers. PRIVACY: REAL-TIME MICROPHONE, ZERO RECORDINGS WatchScope analyses the audio signal in memory and discards it instantly. No audio sample is ever recorded, saved or transmitted to any server. Your personal data (collection, measurements) is encrypted with TLS 1.3 and hosted on EU data centres certified ISO 27001. In-app account deletion, GDPR Art-17 compliant. INVITE A FRIEND, GET ONE MONTH OF PRO FREE Bilateral referral programme: whoever accepts your invitation gives you one month of Pro, and receives one too. Up to 12 redeemed invitations. FREE RESOURCES Complete in-app manual + 8 explanatory guides (reading measurements, magnetism, positions, water resistance, COSC, calibration) also available at https://watchscope.app/resources WHY CHOOSE WATCHSCOPE Perfect for modders, essential for collectors who want to check health status before a service, and extremely useful at flea markets to verify calibers on the spot. Download WatchScope and discover the true beating heart of your mechanical watches. Note: the app is designed exclusively for mechanical and automatic watches. It does not work with quartz watches or smartwatches. Measurement performance depends on the quality of the device's microphone and ambient noise.
