Released at the renowned Geneva Watch Days 2021, the H. Moser & Cie Streamliner Perpetual Calendar is a new timepiece that is filled with hidden details and is powered by a newly developed manually wound movement. A purely minimalist timepiece, the new H. Moser & Cie Streamliner Perpetual Calendar uses the hour indices to mark the months via a small red and white central hand (1 o’clock for January, 2 o’clock for February, and so on). Aligned on the crown, the date window is positioned at 4 o’clock. The current date is displayed by means of two superimposed discs which operate one after the other, from 1 to 15, then from 16 to 31. The date changes in a flash at midnight thanks to an instantaneous date-change mechanism, and it can be adjusted forwards or backward at any time of day.
Enhanced by a sunburst pattern, the fumé dial on the Streamliner Perpetual Calendar is protected by a gently domed sapphire crystal and framed by a 42.3 mm cushion-shaped case crafted from stainless steel with brushed and polished finishes. Like the Pioneer Mega Cool released earlier this year, the Streamliner Perpetual Calendar also features a transparent lacquer logo on the dial. The three-dimensional curved hands indicating the hours and minutes are formed of two sections and feature inserts made from Globolight, an innovative ceramic-based material that contains Super-LumiNova. The red and white outer minute track measures the movement of the central seconds hand. The remarkable power reserve – 168 hours or 7 days – is discreetly indicated at 10 o’clock. Visible via the sapphire case-back, the 2.5 Hz (18,000 vibrations per hour) hand-wound manufacture HMC 812 caliber is meticulously hand-finished with the traditional Moser double stripes and an anthracite grey PVD coating on the balance bridges, train wheels, barrel, and escapement plate.
