This technical file covers the complete quartz mechanism with 6 jewels and rotary stepping motor operating at 1 step per second. Specifications include battery data (SR 716 SW, 1.55V, 21 mAh with 40 months autonomy), performance metrics (0.73 µA current consumption, ±0.40 s/day accuracy, 0–50°C operating range), magnetic field resistance (1500 A/m typical), and precision technical drawings with dimensional tolerances for case fitment, dial integration, and hand assembly. Essential reference documentation for technicians servicing or rebuilding this movement.
Documentation must be downloaded on a computer (PC, Mac, or Linux).
Do not use a smartphone or tablet to download documentation; they generally lack sufficient memory capacity to handle large files, and few users know how to locate the download folder on these devices.
