San Francisco-based Xetum has unveiled its latest limited-edition watch, the Tyndall Carbon Fiber. The timepiece features a 40mm stainless steel case constructed with integrated lugs and grooves around the outer edge, all finished in a matte PVD black. But what really separates this special-edition Tyndall from the standard version is the carbon fiber dial, which is equipped with Superlimova indexes and hands, as well as a 24-hour track encircled by the standard hours track. The watch is completed with Xetum's signature naturally-tanned (and cork-lined) leather strap with butterfly clasp. Limited to just 300 units, the piece is available now directly from Xetum.
