A solar cell module employs a stepped substrate design to prevent piece misalignment and maintain rigidity despite thin, flexible substrates.
A timepiece control unit synchronizes current time via Bluetooth Low Energy or standard electric waves.
Segmented power storage uses a capacitor for rapid startup, preventing hand position loss during slow voltage recovery.
Segmented magnet members enable accurate rotation detection in rotary switches while preventing mechanical damage during axial movement.
An oscillating stepping motor drives star wheels via feed teeth to enable continuous sweep motion in wrist watches.
