The Legacy Machine Split Escapement was first launched in 2017 in four white gold editions with different "frosted" dials, each limited to 18 pieces. The movement developed for MB&F by Stephen McDonnell features the "Split Escapement", with the balance wheel suspended on it own above the dial, while the anchor and escapement wheel are situated under the movement.
In 2019, MB&F introduced a new limited edition of 33 pieces in grade 5 titanium, with a spectacular green CVD-treated dial. The sun-ray dial finish catches the light from alternating angles, constantly changing between blue and green hues – adding a more contemporary edition to the series.
