A 44mm case in zirconium, a lustrous silvery-grey metal with material properties surpassing stainless steel and titanium. A new case profile that emphasises openness and extreme clarity. A specially developed monobloc shock-absorbing system – “FlexRing” – that makes for the most robust Machine ever to emerge from MB&F. The LM Perpetual Engine, designed by Stephen McDonnell, an award-winning perpetual calendar that replaces traditional constructions with an innovative mechanical processor. Three options of PVD/CVD dial-plate colour, including — for the first time in a high-end piece of Swiss watchmaking — atomic orange. And a closely-fitted, integrated strap for the smoothest wearing experience of any MB&F Machine ever.
