H. Moser & Cie. Streamliner Perpetual Calendar

Owners and reviewers widely praise the H. Moser & Cie. Streamliner Perpetual Calendar for its successful fusion of a complex perpetual calendar complication with the collection's signature sporty, minimalist design, highlighting its integrated bracelet's comfortable fit and refined finishing. The manual-wind HMC 812 movement is noted for its seven-day power reserve, with some sources specifying 168 hours. The dial design, particularly the discreet calendar indications and the absence of indices on some Concept variants, is a point of discussion, with some finding it exceptionally clean and others noting potential legibility challenges. The 42.3mm steel case is described as offering a comfortable, retro aesthetic. Overall, owners and reviewers rate the H. Moser & Cie. Streamliner Perpetual Calendar highly for its ingenious complication and distinctive design within the Streamliner aesthetic.
