Description
The Jazzmaster Open Heart invites a glimpse of the mechanics within. An aperture in the green dial reveals the balance wheel of the H-10 automatic caliber at work, a movement that offers an 80-hour power reserve and a Nivachron balance spring.
The 40 mm stainless steel case and integrated-look steel bracelet give the piece a polished, contemporary presence. The case measures 11.05 mm in thickness, with a lug width of 20 mm.
