Premium model from the Edifice line with sapphire crystal and carbon on the dial. A layer of carbon fiber [which is used in racing car tuning] recalls the car’s focus on the brand, and sapphire crystal almost does not glare in the sun and does not scratch. Of the functions there is only the most necessary – a solar battery, which is charged from daylight, a stopwatch with an accuracy of a split second and a date window. In this model, the Japanese introduced a new technology for recharging, reducing the area of the photosensitive panel – now the watch needs even less light for stable charging. The cover with a screw lock not only protects the watch from moisture and small particles of dust, but also simplifies access to the module.
