Carbon Guilloché a unique style employed by Towson watchmakers, featuring engine-turned sub-dials created with a precision-crafted cliché. This design marries traditional watchmaking with a sporty edge, with sharp ‘infinitis’ and deep cuts reminiscent of carbon-fiber texture.

Platinum-Dressed hour-markers, sub-dials and spade- hands. The use of rhodium, one of the Earth's rarest metals, infuses a refined character into the dial's sporty nature. These luminous details complement the high-polish edges on the steel case, fusing sport with luxury.
