Jazzmaster Open Heart Auto 40

★★★★☆Editorial rating 4.0/540 mm

The Jazzmaster Open Heart Auto 40 by Hamilton relies on fine details rather than effects. The 40 mm stainless steel case houses the Calibre Hamilton H-10 (automatic, approx. 80 hrs power reserve). Sapphire crystal and 50 m water resistance put the watch into practical perspective; it is worn on the leather strap at the office and with a suit. For moments when the watch is part of the outfit.
