Jazzmaster Open Heart Auto 40mm Green Dial

An open-heart aperture lets the balance show through the green dial of the Hamilton Jazzmaster Open Heart Auto, reference H32675560. The case is 40 mm stainless steel with a fixed bezel, and luminous hands and markers keep the dial readable. It is 11.05 mm thick.

The automatic H-10 movement provides up to 80 hours of power reserve and can be seen again through the see-through case back. Sapphire covers the dial, and water resistance is 50 meters. The cow leather strap is 20 mm wide with a pin buckle. A dressier watch than the brand's field models, it suits those who like to see the mechanism at work and want an everyday dress-leaning option.
