A Landmark in Industrial Design & Sustainable Horology.

For sale is the legendary Junghans Mega Solar (Model 381/1000). This timepiece is not just a clock, but a historical milestone: it was one of the world's first radio-controlled solar desk clocks, combining German engineering with avant-garde design.

The Design:
Created by the world-renowned studio frogdesign (founded by Hartmut Esslinger). This minimalist masterpiece echoes the iconic "Snow White" design language that Frog Design famously developed for Apple and Steve Jobs in the 1980s and 90s. It is a quintessential example of high-end German industrial design.

The Technology:

Solar Powered: The striking red multi-cell solar panel provides complete energy autonomy. No batteries or winding required!

Radio-Controlled (Mega): Receives the DCF77 atomic signal for absolute precision. It adjusts itself automatically, including Summer/Winter time changes.

Smart Energy Mode: In total darkness, the display automatically switches off to conserve energy. It "wakes up" instantly when exposed to light, retrieving the exact time via radio signal.
