Just released: the latest iteration in the MB&F Legacy Machine Perpetual in a titanium case and a emerald green dial background. Live photographs of the actual watch. 

This is the line extension the the MB&F Legacy Machine Perpetual which was released in November 2015, a perpetual calendar which MB&F founder Max Büsser said he will never make. Why not? Because in his career, he has seen that perpetual calendars are prone to failures, and a recipe for watches being returned for repair. Until he met Stephen McDonnell, who showed him the blueprint of a perpetual calendar mechanism which is fool proof, in the words of Stephen himself, “to create a calendar which is foolproof, you can press the correctors whenever you like. You can manipulate it anyway you like. Whatever you do, you are not going to damage anything.”

MB&F Legacy Machine Perpetua

MB&F Legacy Machine Perpetual in Green.


The movement remains the same brilliant execution by Stephen McDonnell. With the ability to move the calendar forwards and backwards with no fear of damaging the movement. And a calendar which does not revolve around the traditional 31 day calendar. The Legacy Machine Perpetual does not show the 29, 30, or 31 on the short months, taking care of this with an ingenious system which allows the date to advance from the “last day of the month, be that 28, 29, 30 or 31 directly to the 1 of the following month, without any hesitation whatsoever or passing over unwanted days.”


The Legacy Machine DNA is present, suspended balance, and the entire movement mechanism exposed.


This new addition is in a titanium case with the green dial background, limited to 50 pieces. The collection now comprise of white gold purple dial background (25 pieces), white gold with a grey dial background, red gold with a dark grey dial background (25 pieces) and platinum with a blue dial background (25 pieces).

On the wrist, the 44mm diameter case remains comfortable, with the domed crystal feeling snug and organic. And the emerald green dial background providing a beautiful boost in the color.


Here is Stephen McDonnell explaining his creation:
