EDIFICE Scuderia AlphaTauri Limited Edition | Solar powered | A Slim Solar Powered Chronograph created in collaboration with the Scuderia AlphaTauri F1 team, an official EDIFICE partner. 6K dry carbon made of high grade carbon fiber is used for the Inner Rotary Ring. 6K carbon is a bundle of 6,000 woven carbon fibers, and is similar to that used on the wings and floors of Scuderia AlphaTauri’s F1 cars. The coloring of the product is designed based on the team’s navy blue color scheme. The team logo is included on the dial, back of the case, and band. A scratch-resistant sapphire crystal is used in anticipation of rough handling by mechanics.
