Three contrasting subdials give the Mathy Chrono II its motorsport-inspired face. A black tachymeter bezel frames the design, with a steel bracelet and your choice of red, white or green main dial.
H938CHAR has a red dial with contrasting silver, blue and dark subdials. H938CHAS uses a white dial, while H938CHAV has a green dial. Each has a silver-tone 316L steel case and bracelet.
The Ronda 5030D quartz movement provides chronograph timing, small seconds and a date between four and five o’clock. The fixed tachymeter scale converts a timed journey over a known distance into an average speed.
The case measures 42mm in diameter and 12mm thick. Sapphire covers the dial, with Super-LumiNova on hands and markers, a push/pull crown and 10 ATM water resistance.
