Featuring a power-reserve of 55 hours, the CVS3081 calibre is a self-winding chronograph movement that beats at a rate of 28’800 vibrations per hour. Engineered by Cvstos Technology, the movement’s performance is significantly optimized with a high efficiency Tungsten 88 alloy and Grade 5 titanium rotor that can be observed spinning through the sapphire crystal of the open case-back. Water-resistant up to 100 meters, the CVSTOS Challenge III Chrono is fitted with a rubber strap that emulates the dial’s exclusive design.
