Simplicity is at the heart of the latest H. Moser & Cie Streamliner Perpetual Calendar

An ingenious solution to displaying date, month and leap years.

H. Moser & Cie is a brand that has long identified itself through a minimalist design philosophy, often choosing to include elements in the watch’s design only if it was necessary. And with perpetual calendars mostly paired with incredibly busy dials, one might wonder how exactly would this work with Moser watches. Surprisingly in 2005, they managed to revolutionise the complication with the Perpetual 1. This stunning watch displays the perpetual calendar so subtly that to the untrained eye, it would look like a simple three-hander with a date function. Now, they are bringing this incredible complication to the newest collection in their repertoire. Introducing the H. Moser & Cie Streamliner Perpetual Calendar.

The Streamliner collection was introduced only in 2020, and it was the brand’s take on the luxury steel sports watch with an integrated bracelet. The inspiration for its now-iconic shape came from the first high-speed trains of the 1920s and 1930s that share the same name. The curve of the case and its corresponding pattern on the bracelet links were derived from the aerodynamic curves needed to achieve higher speeds back in the day.

The new Streamliner Perpetual Calendar represents a fusing of two icons within the brand creating a piece that can offer traditional watchmaking complications but is infused with the design principles of the modern age. With this collection being one that has a sportier, more dynamic design, a new perpetual calendar fitting of this ethos also had to be designed. And the result was the hand-wound Calibre HMC 812.

Besides the standard three hands on the watch to tell time, there is an additional hand in red and white sitting close to the dial and cleverly using the 12 indices of the watch to indicate the 12 months of the year. The date is indicated as usual in an aperture at 4 o’clock. The leap year indicator however has now been pushed to the back, offering a beautiful wheel to indicate if it’s a leap year or leap year +1, +2 or +3. Along with a redesign, the movement has also been given a modern finishing via the traditional Moser double horizontals stripes and an anthracite grey PVD coating on the balance bridges, train wheels, barrel and escapement plate. The main plate is micro blasted and features anthracite rhodium plating.

For those who can afford its almost CHF 50,000 price tag, they will be glad to know it is not a limited edition but according to H. Moser & Cie, it will be a limited production model.
