Sunrex Banana Reef makes a solar chronograph feel adventurous

The Banana Reef from Sunrex is an unconventional combination of old and new. Its broad, dark cushion-shaped case, contrasting subdials and warm strap recall an era of experimental underwater equipment, while the dial layout remains recognisably that of a sporting chronograph.

Instead of a traditional mechanical chronograph, Sunrex uses its Viluminus solar-powered system. The appeal is practical as well as aesthetic: charging from light avoids the routine battery replacement associated with ordinary quartz watches. Few microbrands pursue solar chronographs with this degree of visual personality, making the Banana Reef a particularly distinctive piece in the category.
