Jazzmaster Open Heart Auto 42mm Beige Dial

A beige dial with an open-heart aperture lets the skeletonized movement show through the face of the Hamilton Jazzmaster Open Heart Auto, reference H32705121. The 42 mm stainless steel case is 11.44 mm thick, and an open see-through caseback offers a second view of the mechanism.

Inside runs the Swiss-made Caliber H-10 automatic, with up to 80 hours of power reserve, so it keeps going through a long weekend on the shelf. A sapphire crystal covers the dial, and water resistance is 5 bar, or 50 meters, which is enough for splashes but not swimming. The stainless steel bracelet closes with a folding clasp. It appeals to anyone drawn to mechanical watchmaking who still wants a refined, dressy profile.
