The MB&F LM Split Escapement, like past Legacy Machine models, features a highly domed sapphire crystal with the balance wheel elevated in the center of the dial side of the watch beating at 2.5Hz (18,000 vph). Where the LM SE differs is from previous models is that the escapement (escape wheel and anchor) portion of the regulation assortment has been moved to the movement side, almost 12 mm underneath the dial.

The dial layout consists of the time at 12 o’clock, the date by hand (which can be set easily with a pushbutton on the side of the case) at 8 o’clock, and the 72-hour power reserve indicator at 4 o’clock.

Each of the four different colored dials is frosted but instead of using acid baths to achieve this rich textured surface like with antique watches, the method used for the LM SE involved manually burnishing the metal surface with a wire brush by hand. And resulting timepieces are quite stunning.

All versions come with a white gold case measuring 44 mm x 17.5 mm and you can choose one of four dials variations limited to 18 pieces each: blue frosted dial with a rhodium-plated movement, ruthenium frosted dial with a darkened ruthenium-plated movement, red gold frosted dial with a red gold-plated movement finish, and yellow gold frosted dial with a yellow gold-plated movement finish.

The retail price is $79,000.
