The Challenge is a big watch. The dimensions of the Tonneau-shaped case is 53.7mm long and 41.0mm wide. It is available in a choice of grade 5 titanium or orange aluminium. Below is the orange aluminium example.
Meanwhile, below is the titanium example. The see-through dial allows you to see the intricate gears of the automatic movement. The power reserve indicator is a nice touch and this alone give it an additional star in my book. Functionality wise, a tachometer is available.
Powered by the Calibre CVSTOS 577, the movement is a 25 Jewel self winding chronograph engine operating at a frequency of 28,800 vibrations per hour. This movement which uses a tungsten and titanium rotor is visible through the sapphire crystal exhibition case back. The propeller like rotor is a beauty.
This side profile shows the 3D effect that was designed into the watch. A real art piece.
It is a pity that this is a LE model. If Cvstos to make a standard production run on this watch with stainless steel as the base material, I’ll bet it can create a strong following to the brand (plus business of course!).
