After three successful years, the HM2 is preparing to bow out with two 18-piece limited series, each fitted with the legendary sapphire crystal case, thereby preserving the exclusive nature of this second MB&F adventure. The backdrop of the HM2-Black SV, composed of a black titanium mainplate, highlights the “engine” framed by an electric green gasket, whose intensity is reflected on the winding rotor visible through the back. Meanwhile, the HM2-Red SV combines red gold with touches of black, metallic silvered shades as well as transparency effects. The result is two superb colour combinations at the heart of these timepieces embodying a horological revolution in terms of both their technology and of the construction principles behind them.
