The 36 mm Jazzmaster Open Heart is a perfect combination of contemporary refinement and exceptional artisan savoir-faire. The perforated design with the utmost precision allows you to admire the Swiss-made Hamilton automatic movement in action while it marks the time and accompanies every important moment of our life. The multiple combinations of dials and straps made of high quality materials offer the modern woman a wide choice. Three-sphere movement with date and power reserve greater than 80 hours, the H-10 features elaborate colimaçon and pearly contrasting patterns for the American Classic models and clean surfaces for the pilot's watches.
