Jazzmaster Open Heart Auto 42mm Blue Dial

Open-heart dials do not always come on a bracelet, but the Hamilton Jazzmaster Open Heart Auto, reference H32705141, has one. The 42 mm stainless steel case holds a blue dial with luminous hands and a window to the balance, and the fixed bezel keeps lines clean. The case is 11.44 mm thick.

The automatic H-10 movement offers up to 80 hours of power reserve and is visible through the see-through case back. Sapphire crystal covers the dial, and water resistance is 50 meters. The 22 mm stainless steel bracelet closes with a folding clasp. It suits those who want a larger dress-leaning watch with a visible mechanism and an all-steel build.
