The MB&F Legacy Machine Perpetual Calendar in White Gold is distinguished by its elegant design and revolutionary engineering. Encased in a 44mm round case made of grade white gold, the timepiece is accentuated with a domed sapphire crystal that reveals a striking skeleton dial set against a purple background.

Visibility is given to an off-centered hours and minutes dial at 12 o’clock, where Roman numerals and blue hands are elegantly displayed. The day and date counters are positioned at 3 o’clock and 9 o’clock respectively, while the month counter is strategically placed at 6 o’clock. Adjacent to the month counter, the retrograde power-reserve indicator and the retrograde leap year indicator are also featured. Central to the design, the flying balance wheel captivates the viewer, adding to the sophisticated aesthetic of the dial.

The movement, manually wound, was ingeniously developed by independent watchmaker Stephen McDonnell. Known as the most user-friendly and trouble-free perpetual calendar on the market, it features an innovative mechanism that prevents the common issues of skipping dates or jamming gears. During periods when the calendar is changing, the adjuster pushers are automatically deactivated, ensuring seamless transitions and functionality.

This particular model, now sold out, is uniquely distinguished by its special purple base plate, making it highly exclusive and limited to only 25 pieces. As such, this version of the Legacy Machine Perpetual Calendar in White Gold not only stands out for its technological advancements and stunning design but also for its rarity and collectability, making it a coveted piece among discerning collectors and aficionados of fine horology.
