Corum Bubble 47 Swoosh – The First Central Tourbillon from Bubble Collection

Luxury Swiss watchmaker Corum updates its Bubble watch collection by unveiling the new Bubble Central Tourbillon. Three characteristics of this piece make it a tourbillon that is one of a kind in watch making. Firstly, the generously proportioned watch case measuring 47 mm diameter provides 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. 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.
