A fusion of two icons, the new H. Moser & Cie Streamliner Perpetual Calendar timepiece innovates on the brand’s new instantaneous date change feature.
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.
Fast forward to 2021 and H. Moser & Cie. revisits this famous movement with its instantaneous date change function in a version that features 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 hand-wound HMC 812 calibre has the same advantages as the HMC 341 calibre, to which a direct-drive central seconds hand has been added. A masterpiece of simplicity and ingenuity, the HMC 812 uses the indices to indicate the months via a small red and white central hand while its guaranteed power reserve of 168 hours is displayed at 10 o’clock on the dial via an indicator.
At 4 o’clock, a window indicates the date, in large format, thanks to two superimposed discs which operate one after the other, from 1 to 15 then from 16 to 31. Aligned on the crown, the date window is positioned at an unusual angle which required the numerals to be tilted to 26-degrees. The date changes in a flash at midnight thanks to the “Flash Calendar” instantaneous date-change mechanism, and can be adjusted forwards or backwards at any time of day. In constant pursuit of minimalism, the leap year indicator is located on the movement side.
Visible via the sapphire case-back, the HMC 812 calibre features an ultra-contemporary finish with 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 microblasted and features anthracite rhodium plating.
The Streamliner Perpetual Calendar, which is equipped with a steel cushion case measuring 42.3 mm in diameter and is water-resistant to 12 ATM, has perfectly rounded curves, evoking the very first high-speed trains whose name it adopts. Designed as a truly sculptural piece, this case boasts harmonious proportions and beautiful aerodynamics. Topped by a subtly domed Glassbox type sapphire crystal that’s echoed by the see-through case-back, these curves extend to the integrated steel bracelet, which is elegantly arced to follow the line of the wrist.
Highly complex in construction, this bracelet has extremely fluid lines, based on organic forms. All the links are articulated and feature a gentle wave combining a vertical brushed finish with polished surfaces. The bezel has a sunray brushed finish; the case has alternating brushed and polished surfaces, with hollowed and satin-finished forms on the sides, in a nod to the traditional unusual shapes typical of Moser cases.
