This new member of the Jazzmaster line is a handsome functional chronograph that makes use of the brand’s H-31 automatic chronograph movement with a whopping 60 hours of power reserve. The 42mm stainless steel case with a dark blue dial, fixed tachymeter bezel, triple chrono registers, and streamlined chrono pushers. There’s anti-reflective coated sapphire glass on the front and sapphire glass on the display back. It comes on an auto-racing inspired perforated blue calfskin leather strap is a perfect match for the dial color. The new Jazzmaster Performer Auto Chrono also comes in white or black dialed versions.
