Streamliner Perpetual Calendar – Black Dial

Complexity, reduced to its purest form.

The H. Moser & Cie. Streamliner Perpetual Calendar merges the brand’s most innovative complication with its signature integrated design—resulting in a timepiece that is both technically advanced and visually refined.

Housed in a 42.3mm stainless steel cushion-shaped case, the watch features a fluid, ergonomic form with an integrated steel bracelet and a distinctive off-centre crown positioned at 4 o’clock. The Blackor fumé dial maintains Moser’s minimalist philosophy, concealing the complexity of the perpetual calendar behind a clean, highly legible display.

Powered by the hand-wound HMC 812 manufacture calibre, it offers a 7-day power reserve and an ingenious calendar system that allows both forward and backward date adjustment at any time, with an instantaneous “Flash Calendar” date change.

Balancing mechanical sophistication with understated design, the Streamliner Perpetual Calendar represents the fusion of two of H. Moser & Cie.’s most iconic achievements.
