Get bench-timegrapher accuracy for under Ā£10. Now works with the iPhone's built-in mic — just rest the phone on the watch, no accessory needed. Faster, clearer live readings with a live signal trace. TG Timer does the rest. Designed for watchmakers and enthusiasts who service their own movements, TG Timer measures the rate, beat error, and amplitude of any mechanical watch using autocorrelation analysis of the tick signal — the same technique used by dedicated bench timegraphers costing hundreds of pounds. What It Measures • Rate — seconds gained or lost per day • Beat error — escapement symmetry in milliseconds • Amplitude — balance wheel arc in degrees • BPH — movement frequency, auto-detected or manually set How It Works Rest your iPhone upright with its bottom edge on the watch crystal (dial up), tap play, and follow the quick on-screen guide. A reading builds on screen within a few seconds and keeps refining live as it listens — a live signal trace shows the individual readings settling onto the answer. Leave it running as long as you like; it never times out, so you can be certain the reading is rock-steady. Optional Contact Mic No accessory is needed — but for the strongest signal, especially in a noisy workshop, you can clip on a piezo contact microphone via a USB-C audio adapter. TG Timer detects it automatically. (Search "piezo contact microphone" and "USB-C audio adapter" — typically under Ā£30.) Movement Presets Choose from a built-in library covering ETA, Sellita, Miyota, Seiko, Rolex, Omega, and more. Selecting a preset automatically sets the correct BPH and lift angle for accurate amplitude readings. PDF Reports Generate a clean PDF report with watchmaker and customer details, watch brand and movement, position, notes, and the full rate history chart. Share directly from the app. Designed for the Workshop • Screen stays on during a measurement run • Portrait-locked for stable bench use • Dark interface — easy on the eyes under workshop lighting • No account, no subscription, no data collected
