MB & F LM1 Alain Silberstein

MB&F like to fool around in their kitchen. They often invite some friends over to make some nice diners together. This time is was an old friend of the brand Alain Silberstein who did his magic on the Legacy Machine 1.

Alain Silberstein is an architect who started making watches in the ’90s. His inspiration for the watches came from architectural movements, like the German Bauhaus. Alain Silberstein is no longer making watches. But perhaps with this new collaboration, the Swiss world will be coloured again with his expressive designs.

2009 was the year of the first project with MB&F, the HM2.2 “Black Box” was born.

LM1 Alain Silberstein


The 42.5 mm case comes in three different versions, Titanium (grade 5), 18K red gold and a Titanium (grade 5) with a black pvd. Simular to all the LM models is the domed shape of the sapphire. The two crowns on both sides are designed in a stare like shape. They are actually two triangles put together. This is signified as pure Silberstein features.


Its almost a cliche to say, but this is where the magic happens. Silberstein plays with ways to finish materials. Using layers underneath finished in matt and therefore highlighting parts that are on top with a high gloss finish. Nice example of this are the two dials showing the time. These dials have a matt finishing making the high gloss hands pop out. Also the use of colour make this a really readable and likeable watch. The red colour of the hour hands has been chosen because this is the first thing you want to know when looking at your watch.

The iconic power reserve hold a yellow sphere, red cube and a blue cone. Giving this three dimensional indicator a great look on the dial.

The piece the resistance is the sapphire bridge which holds the balance wheel centered on the dial. It took the engineers almost two years to figure this out. Alain requested this in sapphire to give the balance wheel the stage it deserve, full spotlights.



The movement of the LM1 is made by Jean Francois Mojon (Chronode) together with Kari Voutilainen. The concept was based on sketches made by Maximilian Büsser. The balance wheel and spring at the very heart of any mechanical watch movement are responsible for regulating timekeeping accuracy. Büsser has long been fascinated by the large slowly oscillating balance wheels of antique pocket watches –18,000 bph compared with the 28,800 bph common today – so it was no surprise this was the starting point from which to let his fertile imagination roam free. What was surprising, though, is just how radically he re-interpreted tradition by relocating the balance wheel from its more usual position hidden at the back of the movement to not just the top of the movement, but floating above the dials!

While the location of Legacy Machine N°1’s regulating organ may be considered avant-garde, ‘tradition’ is upheld by the large 14mm diameter balance wheel with regulating screws specifically developed for MB&F, balance spring with Breguet overcoil, and mobile stud holder.

Another very special feature of the LM1 movement is the ability to set the two time zones completely independently. The vast majority of dual time zone movements only allow the hours to be independently adjusted, a rare few offer setting to the half hour. Legacy Machine N°1 allows both hours and minutes of each dial to be set to whatever time the user wishes.

The world’s first vertical power reserve indicator on LM1 is driven by an ultra-flat differential with ceramic bearings allowing for a slimmer complication and a more robust and longer-wearing mechanism.


With the LM1 range MB&F has a very strong line up already, this new edition fits perfectly. It seems every collaboration Maximilian take in to his hands ends up as an amazing result. The watches Alain Silberstein made in the past, with their iconic designs, seems to come alive again. Let’s hope more watches will come after this and the brand will once again live up.
