Only 100 Pieces are Available Per Variant A tribute to Hexham—a historical town renowned for its medieval abbey and as a gateway to Hadrian’s Wall, this 43mm timepiece is a bold statement that bridges history and pioneering craftsmanship. At its heart lies a custom-engineered 'wandering hours' complication, where three rotating hour discs glide across a central carousel, reimagining time in a striking, three-dimensional display.
