Revealed at Baselworld 2018, Laurent Ferrier’s Minute Repeater is a rare horological complication piece manufactured according to the highest standards in fine watch making. This timepiece comes in limited edition and just five will be produced over the two next years.
To ensure the sound would be as beautifully rounded as possible, the case has been made of steel, a choice of material accentuating the chime and endowing it with a clear, light tone. So as to prolong the listening pleasure, the chime lasts is 17 seconds for the longest indications. A major highlight of this complication is well-modulated spacing of the hours, quarters and minutes chimes.
The striking mechanism is activated by a sliding bolt built into the left side of the case-middle. Tiny hammers strike a two-pitched gong to sound the hours, quarters and minutes. A minute repeater watch strikes on demand a low-pitched note for each hour, a double high- and low-pitched note for the quarters, and a high-pitched note for every minute that has elapsed since the last quarter.
For example, if the time is 11:59 the minute repeater will sound 11 low tones representing 11 hours, 3 sequence tones representing 45 minutes and 14 high tones representing 14 minutes after 45 minutes. The time is struck by small steel hammers on differently tuned gongs – steel coils curving in a circular shape around the movement.
Laurent Ferrier chose a very classically designed movement with a Swiss lever escapement and traditional materials for a complication whose originality lies in crystal clear sound and a long chiming sequence. This manual winding caliber has an 80 hour power reserve.
This new movement features signature Laurent Ferrier characteristics such as a winding pawl with a long blade, a distinctively shaped balance-wheel, a Côtes de Genève motif as well as finely cut bridges. The note-shaped bridge on the inertia flywheel is a delightful nod to the function of the model. The classically shaped hammers with their stark outlines are aligned on a bridge featuring distinctive interior angles. Through the sapphire crystal case-back, one can admire the views of the finishing of the movement with its manually chamfered angles and polished screw heads.
For the Minute Repeater, Laurent Ferrier entirely adapted the 40mm School Piece case to ensure perfect harmony and balance between the movement and the timepiece.
The gold Assegai hands and baton-type seconds hand retain their characteristic shape. Laurent Ferrier has treated the Minute Repeater dial with a 6N red gold colour, featuring copper glints thanks to the vertical satin-brushed finish that is a favourite with the Maison. The silver-toned small seconds subdial at 6 o’clock is adorned with a snailed finish.
