Beneath the dial, the reliable Epson AS32 solar quartz movement draws its energy directly from light. An integrated solar panel converts both natural and artificial light into electricity, storing it in a long lasting rechargeable power cell.

Once fully charged, the watch runs for up to four months, even when kept in the dark. When the power reserve runs low, the seconds hand begins moving in two second intervals to indicate that the watch needs more light. Simply place it in the light for about ten minutes, and it will begin recharging and continue running reliably.

With an accuracy of -20/+20 seconds per month, the Epson AS32 delivers precision, sustainability, and dependable performance. A perfect match for the timeless character of the Hamburg Solar.

Thanks to the quick-change system, you can give your timepiece a new look in just 10 seconds:

1 — Slide the pin of the spring bar inwards.

2 — Pull the strap off the watch.

3 — Put on a new strap by sliding the pin inwards again and inserting the spring bar one after the other into the holes in the case.
