Seiko Time Creation QP-400GS Solar-Powered Controller
Manufacturer: Seiko Time Creation Inc.
Model: QP-400GS
Overview
The GNSS receiver automatically receives GNSS signals from GNSS satellites to synchronize the time of the clock.
The energy generated by the solar panel is stored in the capacitor inside the clock controller, powering the clock unit during the nighttime.
