CALIBRE LF270.01

Exclusively developed by LAURENT FERRIER, the calibre LF 270.01 is the house’s second 

automatic calendar movement. It subtly pairs a homage to our Natural Escapement Micro-Rotor 

with a sportier, more assertive style, and has been entirely designed, decorated, assembled 

and adjusted in the LAURENT FERRIER workshops. 

This new calibre features a Swiss lever escapement and uses an automatic winding system 

via an off-centred micro-rotor. A unidirectional ball bearing replaces the traditional pawl 

system, giving this movement significant benefits in terms of shock- and vibration-resistance. 

The micro-rotor features an oscillating weight made from 950 platinum, which is positioned 

directly between the mainplate and the rotor bridge to ensure ideal stability and to maximise 

its winding potential. When completely wound, this calibre offers a power reserve of over 

72 hours. 

Careful attention to detail

A sapphire crystal case back reveals an impeccably finished movement whose architecture 

echoes the main codes of the brand’s first automatic movement. 

Every single calibre LF 270.01 requires over 139 manual finishing operations. In particular, the 

bridge of the micro-rotor movement is meticulously decorated by hand, with softened angles 

finished with Gentian wood and Diamantine, and a mirror-polished surface. The movement also 

features several interior angles, multiple zinc-polished surfaces and many instances of satin-

brushing and circular-graining, all produced by hand in the LAURENT FERRIER workshops.

The ruthenium-treated bridges present a horizontal satin-brushed finish. These decorative 

touches combine to give this automatic movement a dynamic look that is as modern as it is 

intense. When paired with the dark hue of the grade 5 titanium adorning the bracelet and case, 

it enhances the sharp and sporty style of this new exceptional timepiece.
