Official description

In 2005, H. Moser & Cie. marked its return to Haute Horlogerie by revolutionising the perpetual calendar with the Perpetual 1. Distinctly minimalist and understated, to the non-expert eye, this movement simply looks like a calibre with three hands plus the date. Simple in appearance and yet so ingenious, it immediately earned its place as one of the Manufacture's flagship products. In 2021, H. Moser & Cie. is innovating and revisiting this famous movement with its instantaneous date change function as a version featuring four central hands and a resolutely contemporary look. Not only that, the brand is making this timepiece part of its Streamliner collection to create the Streamliner Perpetual Calendar. The fusion of two icons.
