Opera SM Electron
Model3 / 4A unique Opera No. 1/1 watch with a precisely hand-engraved dial. This work of art is available only as this single original. On request, however, a piece can be made to individual specifications, which the engraver will execute in similar quality, whether on the dial surface, on its appliqués (for models designed with appliqués, such as Retron, Regutron, etc.), on the watch movement, or directly on the outside of the case.
