MB&F celebrates the pioneering works of past masters and complications with the Legacy Machine No. 2. Suspended high above the dial, the double “flying” balances are in fact the most visible parts of two fully independent regulating systems, each beating at its own rate. The planetary differential sits proud on the surface, supported by a stunning double-arc mirror-polished bridge. The complex differential is the key element in the double regulator system: the rates are averaged out by the mechanism, which drives the blued hour and minute hands of the white stretched-lacquer sub dial. The two flying balances and their escapements are identical mirror images, right down to the position of the stud holders pinning their balance springs. Exquisitely finished, the LM2 is an object lesson in symmetrical simplicity. Limited to 18 pieces.
