Swiss watchmaker Corum has unveiled the Admiral’s Cup Challenger 44 Chrono Rubber collection. Its vulcanized rubber cases come across as appealing and the watch comes in varied shades – red, blue, black and white. It is a limited edition collection with features such as its characteristic twelve-sided design and the inner bezel ring adorned with nautical pennants. Its hands, minute numerals, chronographs and chevrons are highlighted by luminescent white, grey or red allowing night-time readability. The timepieces are powered by the mechanical automatic CO753 movement that is chronometer-certified by the COSC. It has three counters and a date window at 4.30 on its display and is water-resistant to 30 meters for the white versions and to 100 meters for others. The transparent back shows a CORUMengraved oscillating weight.
