Opera BM Tiger
Model4 / 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 also be made to an individual brief, which the engraver will then 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 outer surface of the case.
