MB&F Horological Machine No4 Final Edition. Estética inspirada no conceito Stealth (furtivo).
O HM4 demorou três anos a desenvolver e os seus 300 componentes - até ao mais pequeno pormenor, como os parafusos - foram desenvolvidos especificamente para este e só este calibre, que a marca classifica de "anarquista".
Dois tambores de corda dispostos horizontalmente estão ligados a duas transmissões verticais, que transferem a energia (72 horas de autonomia) para dois mostradores, que indicam horas e minutos, de um lado, e a reserva de corda, do outro.
Inspirada na aviação, a caixa do HM4, (54 mm x 52 mm x 24 mm) em titânio revestido a PVD negro, é composta por três partes: dois corpos em forma de turbina, ligados por uma ponte horizontal, que alberga o calibre, visível através de janelas em vidro de safira, e a própria secção central da caixa.
Da marca:
"If you look at any plane or boat designed with stealth in mind, they usually look to all intents and purposes anything but inconspicuous. And the stealthier they are, the more strikingly – radar excepted – obvious they are. Lockheed’s sensational F-117 Nighthawk was the world’s first operational stealth aircraft. While visually unmistakable, the F-117’s flat, faceted panels reflected radar away from detection and its dark surfaces blended seamlessly with the night sky. The Nighthawk was also revolutionary in the fact that its structure was a mix of aluminium and titanium. Like the iconic F-117, HM4 Final Edition features square angular panels, dark surfaces and high-tech titanium. It looks fast. It looks menacing. And to date there have been no reports of a Final Edition being picked up by radar, so that’s the ‘stealth’ box ticked as well. The aviation-inspired case and engine of Horological Machine No. 4 – first launched in 2010 – are one. This 2013 'Final Edition' case blends high-tech titanium for its lightweight and strength with a sapphire centre section offering a view into the engine. Black PVD provides the titanium with its shadowy cloak of concealment without blocking the light playing off the contrasting matte and highly polished surfaces".
"The sleek aerodynamic form of HM4 has its roots in Maximilian Büsser's childhood passion for assembling model plane kits, though none looked remotely as futuristic as these. The striking transparent sapphire section of the case requires over 185 hours of machining and polishing to transform an opaque solid block of crystal into a complex, exquisitely curved panel allowing the light to come in and the beauty of the HM4 engine to stand out. Every component and form has a technical purpose; nothing is superfluous and every line and curve is in poetic harmony. Articulated lugs ensure supreme comfort. Highly legible time is a fringe benefit".
O HM4 Final Edition é uma edição limitada a oito exemplares e encerra a série HM4, que foi limitada a 100 exemplares no total dos modelos (imagens de versões anteriores em baixo).
