Former professional diver, paratrooper and talented photographer, Frank Huyghe the founder of Ralf Tech drew his inspiration from the underwater and marine world and thus offers a different vision of watchmaking. The watches are submersible, masculine, robust and precise. We can find these pieces on famous skippers’ wrists such as Armel Le Cléac’h or Thomas Coville but also on the special forces operators’ wrists from many countries including France.
