With the combination of a striking matte 316 stainless steel case, a calm jet-black dial, low-reflection sapphire crystal, and precise index arrangements, this chronograph is easy to read during the day. At night, the color-arranged tritium luminous elements ensure excellent readability. Even a brief glance in the dark shows the exact time clearly.
In terms of optics, the tachymeter lives up to the positive sporty background of all BOMBFROG watches. The deep relief engraved tachymeter scale fits, without being obtrusive, ideally to the overall impression of the high-quality Chronographs.
The chronograph functions qualify the time to be measured in seconds and minutes. The large highlight seconds hand in red, with a Tritium tube, stops the time exactly to the second.
