Christophe Claret Concertino

Christophe Claret Concertino is an Haute Horlogerie minute-repeater watch featuring a completely redesigned movement with a unique regulator.

It belongs to the family of traditional complications watches, the first of the four collections of the independent Swiss brand. It is inspired by previous creations by Christophe Claret, while once again pushing the limits of what is possible in this area. Its CRM89 caliber is an entirely redesigned composition, from the mainplate to the bridges, including the flywheel which regulates the minute repeater mechanism.

With a frequency of 3 hertz (21,600 vibrations per hour), this single barrel mechanical-hand wound movement provides a power reserve of around 60 hours. The minute repeater activation is traditionally made through a sliding pusher on the left side of the case. The choreography of the two hammers is visible through the sapphire crystal back of the watch.

Christophe Claret is the designer of this four-branch balance wheel which offers an inertia / weight ratio close to the ideal balance: although very complex to manufacture, this aerodynamic balance is easy to adjust and balance.

Special care has been taken in the Concertino “Cathedral” bells. This type of bell has the particularity of going around the movement twice in order to produce melodies that are longer, clearer and more powerful.

Excellent technical-know is required for their manufacture in drawn steel, for their assembly and tuning. They benefit from a patented in-house invention which blocks significant vibrations despite their exceptional lengths and thus prohibits all parasitic noises. The balance cockbridge has a micrometric adjustment system that is also patented.

Concertino is available in 5N red gold or grade-5 titanium, and its fully customizable dial makes it unique each time. Measuring 45mm in diameter, the case harmoniously combines the polished and satin finishes of 5N red gold or titanium, highlighting the play of lights.

Christophe Claret Concertino features a large dial, set with an immense sapphire crystal under a finely satin-brushed bezel. The dial (enamelled, engraved, set and / or guilloché) also magnifies the light and dark, with its unique nuances of hues and personalized materials.

The early Concertinos display an ornamental hand engraving (nearly 1.5 mm) of two dragons – protectors of the Sun, an 8 mm pigeon’s blood ruby, in its rose gold livery or protectors of the Earth, a sapphire 8 mm blue, in its titanium livery.

The transparent case-back affords the view of the exceptional architecture of the movement. On the back side, the watch features the famous stepped and skeletonized Charles X bridges, signatures of Christophe Claret. The movement is in micro-blasted and rhodium-plated nickel silver for the Concertino grade 5 titanium version, or 4N red gold plated for the 5N Gold Concertino version.
