The central seconds appeared as a practical evolution, offering a direct and precise reading of the seconds thanks to a more detailed graduation of the dial.
Widely adopted during the Second World War for military and technical purposes, it soon became a benchmark of functionality.
Each model in this collection is equipped with a vintage mechanical movement, restored and hand-decorated in my workshop in Porrentruy, combining rigor and authenticity.
