The watch the maison is built around: a 38 mm steel case 8.9 mm thin, polished on the bezel and brushed on the flanks, with a domed sapphire crystal and long faceted lugs that follow the wrist. Applied baton indices and dauphine hands are cut and polished in-house; the minute track is printed in a single pass so the line never breaks.
Inside is the hand-wound calibre VH-10, 2.9 mm thick with a 70-hour reserve from a single barrel. Turn it over and you see Côtes de Genève across the bridges, perlage on the plate, flame-blued screws and an anglage polished by hand - regulated in five positions to −2/+4 seconds a day.
