Framed by a black tachymeter ring, the vivid blue dial features three black subdials, including 24-hour and power reserve indicators, a date calendar, a red chronograph seconds hand, and LumiBrite hands and markers. Crafted of stainless steel with tri-fold push button release clasp, and curved sapphire crystal with anti-reflective coating on the inner surface. 10 bar, 100M Water Resistant
