CORUM – BUBBLE 47 Central Tourbillon


CORUM BUBBLE 47 SWOOSH Central Tourbillon Automatic Titanium

The Bubble is featuring its first central tourbillon

Corum’s Bubble is playing on its charms and roundness and is ready to welcome a central
tourbillon. The famous age-old complication has been given a new lease of life with a playful and
contemporary touch. Could this mark the beginning of a Fine Watchmaking collection for the

Bubble?


The tourbillon was designed for pocket watches. On wristwatches, its function is purely aesthetic.
With the magnifying effect provided by the Bubble's domed crystal, a tourbillon has never been as
present or as powerful on a wristwatch. This novel approach provides us with a glimpse of the
possibility of Fine Watchmaking for the Bubble.”

That’s how Jérôme Biard, the CEO of Corum, is unveiling the new Bubble Central Tourbillon. Three characteristics of this piece make it a tourbillon that is one of a kind in watchmaking. First, the piece is generously proportioned. The Bubble’s 47 mm provide ample space for the tourbillon to fully express itself. Then there’s the central position of the tourbillon, a complex technical choice, since it requires an inline movement construction.

The complication nevertheless features a pallet that is not soldered and makes it possible for this centrally placed tourbillon to immediately catch the eye. The absence of hands on the watch is also noteworthy. The hours and minutes are moved to the flange, where they are indicated by two triangular markers: one in black that indicates the minutes, with a second one indicating the hours. The tourbillon itself indicates the seconds.

Finally, there is the Bubble's domed sapphire crystal. Corum has frequently played on the magnifying effect in the centre and lightly deforming effect on the sides to create different visual effects. That’s no different here. The peak of the sapphire crystal acts as a magnifying glass on the tourbillon, which is located just underneath, a natural way of bringing out the slightest details.

Taking advantage of this original watchmaking effect, Corum has depicted its key logo in the middle
of the tourbillon, on its upper bridge. This delicate engraving is appearing for the first time, and in
great detail. It’s worth noting in passing that Corum has opted for an authentic tourbillon, such as it
was patented in 1801, and not a carrousel or flying version. It is powered by an automatic movement
with a bidirectional oscillating weight and, above all, two barrels in series that promise both excellent
isochronism and a 65-hour power reserve.

In keeping with the spirit of the Bubble, the Central Tourbillon is quirky and playful, not a
conventional evening piece. Designed for everyday life, and beating at 28,800 vibrations per hour (4
Hz) for enhanced precision, it is made of titanium to ensure both lightness and sturdiness.
Three different versions are available: black & pink gold on rubber, natural titanium & blue on rubber or on Milanese mesh made from grade 5 titanium, for a perfect aesthetic and technical consistency that is rare for a Milanese mesh watch strap. Water resistance is guaranteed to 100 metres, another rarity for a piece with a tourbillon, providing the Bubble Central Tourbillon with an urban, sporty and contemporary character.
