Jazzmaster Open Heart Auto 40mm Blue Dial

Blue dial and an open-heart window define the Hamilton Jazzmaster Open Heart Auto, reference H32675540. The 40 mm stainless steel case has a fixed bezel, and luminous hands keep the time readable. The case is 11.05 mm thick.

Powering it is the automatic H-10 movement, which holds up to 80 hours of power reserve and is also visible through the see-through case back. A sapphire crystal covers the dial, and water resistance is 50 meters. The cow leather strap is 20 mm wide and closes with a pin buckle. It is a dressier take on a mechanical watch, aimed at wearers who enjoy seeing the movement in action and want a calm blue face.
