Legacy Machine 101 Is The Very Essence Of MB&F

MB&F’s Legacy Machine 101 (LM101) series was first launched in 2014. As suggested by its “101” name, it focuses on the essentials of a mechanical wristwatch, contained in one of their most compact Machines with a case diameter of 40mm.

At the time, the LM101 movement was also the first entirely conceived by MB&F’s in-house engineering team. The latest series evolves with technically and aesthetically-upgraded versions distinguished by colourful dial plates, including a stainless steel version. Focusing further on the essentials, the bezel and “Legacy Machine” engraving on the dial withdraw to highlight the time and power reserve, indicated on slightly larger subdials; and the star of the show, the signature “flying” balance wheel, inherits a double hairspring.

Legacy Machine 101 embodies and accentuates the very essence of what is essential in a wristwatch: the balance wheel, which is responsible for regulating precision; how much power remains in the mainspring, which indicates when it needs to be next wound; and of course, the time.

Visually, LM101 is dominated by the monumental suspended balance wheel, its sedate oscillations drawing the eye ever closer. Two pristine-white sub-dials hover just above the fine sunray-engraved movement top plate. At the top right, highly legible hours and minutes are displayed by beautiful blued-gold hands contrasting against the immaculate white, while the 45-hour power reserve indicator is displayed in a smaller, but similar sub-dial below.
