Since it first made its entry in 2015, the LM Perpetual has been offered in a variety of case materials. It has also been awarded the Best Calendar Watch Prize at the GPHG (Grand Prix d’Horlogerie de Genève) in 2016.

Reinventing the perpetual calendar complication (a collaboration between MB&F and independent Irish watchmaker Stephen McDonnell), the LM Perpetual has taken strides forward with its unique complication and masterful watchmaking. Keeping in tune with its earlier editions, the LM Perpetual in Yellow Gold features a fully integrated, purpose-built, 581-component movement that looks fantastic from the front and back. It does not feature a module or base for the calibre but houses a revolutionary new system (mechanical processor) that will calculate the number of days in a month. The dark blue skeletonised dial houses the hours and minutes at 12 o' clock, the day of the week at 3 o' clock, power reserve indicator at 4 o' clock, month at 6 o' clock, retrograde leap year indicator at 7 o' clock and finally the date at 9 o' clock.

Crafted from 18k yellow gold case (which goes perfectly with the dark blue dial), the LM Perpetual Yellow Gold is limited to just 25 pieces and is available in a blue hand-stitched alligator strap with gold folding buckle that matches the 18k Yellow Gold case.
