With a 47 mm black PVD-treated grade 5 titanium case, the latest addition to the Bubble Chronograph collection employs a "diablo" dial with a mirror-polished back. The indications are distributed as follows: hours and minutes in the centre, chrono seconds at 3 o'clock, continuous seconds at 9 o'clock, date window at 6 o'clock. The famous domed sapphire crystal is anti-reflective. The watch, produced in a limited series of 88 pieces, is driven by the CO 771 calibre (13 ¼'' diameter, 28 jewels, 28,800 vibrations per hour, 55-hour power reserve), mechanical with automatic winding and visible from the back, thanks to an anti-reflective sapphire crystal porthole. Water-resistant to a pressure of 10 atmospheres, the Corum Bubble 47 Chronograph is fitted with a black vulcanised rubber strap.
Price: 6,900 euro.
