After 10 years and 15 different clocks, the L’Epée 1839 X MB&F Albatross is by far the most technically audacious co-creation by the two companies. Totaling a whopping 1520 components, Albatross features a striking hour function —chiming both the specific hours on the hour and a single strike on the half-hour— and an automaton composed of 16 pairs of propellers that launch into action every hour.
