Two-Minute Calibration

I shifted past the fastener bins to inspect a display rack of analog mechanical timers. You asked for more, specifying a calibrated two-minute series; precision timing requires reliable escapement. I approached a compact circular wind-up timer resting flat against a carded backing. Bracing my left boot against the chrome rim, I gripped the knurled center dial and rotated it clockwise past the stop, then aligned the red arrow precisely with the two-minute hash mark. The internal gear train engaged instantly, releasing a steady, metered cadence through the metal shelf. When the cycle expired, the internal bell struck once with sharp resonance. Interval confirmed functional. Telemetry expanded.
