Light is their source of energy, and Arctic beauty serves as a source of inspiration. The wristwatches in the BERING SOLAR COLLECTION beat in harmony with nature, as their energy source is environmentally friendly and unlimited: light! The solar cell under the dial of the BERING wristwatch converts not only sunlight, but any kind of light into electrical energy, which is stored in a rechargeable secondary battery. There is no need to change batteries, as is usually the case with quartz watches. The watches in the SOLAR COLLECTION have a power reserve so that they can run for 6 to 12 months once fully charged - even if they are kept completely in the dark during this time. Scratch-resistant sapphire crystal, a case and bracelet made of lightweight titanium and the masterful processing of high-quality materials characterize this watch collection. A special design element that catches the eye are the raised indices in an easy-to-read 3D look, which protrude from the water like icebergs. BERING offers an international guarantee of three years for the high quality of all wristwatches.
