Naos Solar dark green

Beneath the dial of the Naos Solar lies a fine solar panel that converts sunlight and artificial light into energy. This energy is stored in a rechargeable cell that replaces the conventional battery. When fully charged, the watch runs for up to four months, even when kept in the dark.

The stored energy powers the precise Epson AS32 solar quartz movement, whose quartz resonator ensures accurate, steady motion of the hands. The Naos Solar combines the precision of traditional watchmaking with the independence of modern solar technology.

A practical detail: if the second hand moves in two-second intervals, the energy cell is running low. Simply place the watch in bright light for about ten minutes, and it will recharge and resume normal operation – reliable, maintenance-free, and always ready to wear.

Beneath the dial is the reliable Epson AS32 solar-powered quartz movement, which draws its energy directly from light. The built-in solar panel converts sunlight and artificial light into electricity and stores it in a long-lasting energy storage unit.

Once fully charged, it runs for up to four months. When the energy storage runs low, the second hand moves in two-second intervals, signaling that the watch needs more light. After a short time in the light, it resumes running continuously.

With a rate accuracy of –20/+20 seconds per month and its characteristically smooth operation, the Epson AS32 stands for precision, sustainability, and reliability—a perfect match for Naos’s clear standards.
