Yup. Vertical power reserve.
Below is the official press release from their site.
Wild, extreme, outrageous, unrestrained: all might be used to describe MB&F's futuristic Horological Machines, but traditional, classical… round? With its monumental central balance; superlatively finished movement; completely independent dual time zones; unique vertical power reserve indicator and elegant annular case, Legacy Machine No.1 (LM1) is a tribute to the great innovators of traditional watchmaking; and above all, an authentic three-dimensional MB&F Machine.
Legacy Machine No.1 was conceived when Maximilian Büsser started fantasising: "What would have happened if I had been born in 1867 instead of 1967? In the early 1900s the first wristwatches appear and I would want to create three-dimensional machines for the wrist, but there are no Grendizers, Star Wars or fighter jets for my inspiration. But I do have pocket watches, the Eiffel Tower and Jules Verne, so what might my 1911 machine look like? It has to be round and it has to be three-dimensional: Legacy Machine No.1 was my answer."
In fidelity to high-quality 19th century pocket watches, LM1 features a sedately oscillating (2.5 Hz), large diameter balance with traditional Breguet overcoil suspended from majestic twin arches; its enigmatic regulating mechanism in full view, but without apparent connection to the movement. Both the hours AND the minutes on each of the two sub dials can be set completely independently of each other – dual time zone complications usually do not allow independent adjustment of the minutes – their domed dials further reinforcing visual references to the golden age of watchmaking (1780-1850). Looking like a miniature sextant, a world-first vertical power reserve indicator keeps track of available power while providing a visual three-dimensional counterpoint to the graceful arches supporting the balance.
Gazing down through Legacy Machine No.1's crystal clear bubble sapphire dome to the micro-mechanical fantasy below, it's easy to imagine Jules Verne’s Captain Nemo looking upon the mythical underwater city of Atlantis.
Legacy Machine No.1's transcendental in-house movement bears testimony to the enormous talent of its creators. Jean-François Mojon and his team at Chronode (Best Watchmaker Prize at the 2010 Grand Prix d’Horlogerie de Genève) met the considerable challenge of developing the calibre for LM1 from a blank sheet, while acclaimed independent watchmaker Kari Voutilainen took responsibility for the aesthetic design and for strictly ensuring the utmost respect for tradition and finish. Immaculate Geneva waves, highly-polished gold chatons and bridges with impeccably executed bevels following deliberate internal angles (which cannot be finished by machine) showcase the movement's absolutely peerless fine-finishing. The movement of Legacy Machine No.1 proudly bears the names of both its creators, and is the first calibre other than Voutilainen's own to bear his name.
