Swiss watchmaker Corum is marking Eid Al Fitr with the most complicated of its line of Bubbles watches to date: the Bubble Tourbillon Chronograph and Bubble Tourbillon GMT. Each line is limited to just five watches.

Touted as the most complicated Bubble ever, the Bubble Tourbillon Chronograph is self-winding, powered by the CO398 movement exclusive to Corum, a press release said.

Shaped like the Corum key logo, the tourbillon cage is visible at 10 o’clock, making a revolution every one minute. Operated with two pushers on the case, the chronograph records the seconds on the central axis, while the minutes are counted on the register at six o’clock.

The chronograph is controlled with a column wheel that functions as an on-off switch. This is both more refined and complex than the cam found in industrially produced chronographs, said Corum.

Equipped with the similarly exclusive, automatic CO397, the Bubble Tourbillon GMT features a tourbillon regulator and a second time zone display. Displayed on a rotating disc at six o’clock, the second time zone can be swiftly advanced in hourly intervals via the pusher at four o’clock. The second time zone is read in tandem with the day and night indicator at eight o’clock.

To emphasize the optical effects of the massive Bubble sapphire crystal, both tourbillons are fitted with pale grey dials decorated with a concentric guilloche that accentuates the contours of the dial, the press release added.

The Bubble Tourbillon GMT and Tourbillon Chronograph both feature hand-finished movements decorated with traditional techniques like chamfering and straight graining. They share the same, iconic Bubble watchcase, hewn from a block of 18k rose gold and polished to a mirror finish, Corum concluded. –TradeArabia News Service
