Press Release

As an inexhaustible source of energy, the sun has been an inspiration for Junghans solar-powered watches as far back as the 1980s. The Max Bill MEGA Solar perpetuates this tradition of sustainability in a particularly attractive and uniform style. A sustainable subsistence involves prudent utilisation of resources. The new Max Bill MEGA Solar from Junghans epitomises this holistic approach.

The titanium case ensures that the watch is feather-light, extremely sturdy and is harmoniously compatible with the skin. Its leather straps are vegetable-tanned and feature velvety soft Alcantara on the inside. The case back arches perfectly against the wrist to complete the extraordinary wear comfort of the timepiece.

A completely new radio-controlled movement from Junghans guarantees maximum precision and is exceptionally energy-efficient: Even when completely drained of power, the watch will become fully functional again after only eight minutes of direct exposure to the sun. Moreover, the movement has a power reserve of up to three years. A perpetual calendar, automatic conversion from summer time to winter time and automatic adjustment of the time zones using the crown or – on a global scale – via time synchronization with the latest version of the Junghans MEGA App.

Even the design of the watch is sustainable due to Junghans’s collaboration with the artist Max Bill over the years. Junghans designed a convex dial with a solar cell specifically for the Max Bill MEGA Solar, merging into the overall design of the watch.

The Max Bill MEGA Solar timepiece incorporates natural materials, innovative technologies and puristic design. What more could you ask for?

This timepiece retails at SGD 1,460, inclusive of tax for its leather strap editions and SGD 1,590, inclusive of tax for its bracelet edition.
