Hamilton Jazzmaster Open Heart Automatic Blue Dial Steel Strap Men's Watch H32705142
The Hamilton Jazzmaster Open Heart Auto combines Swiss watchmaking tradition with contemporary flair. Its partially skeletonized blue dial reveals the beating automatic movement at the 12 and 7 o’clock positions, creating a striking interplay of mechanics and design. This detail transforms a classic timepiece into a statement of refined openness.
Long-Running Precision At the core lies the H-10 automatic calibre, known for its impressive 80-hour power reserve. The inclusion of a Nivachron™ balance spring enhances resistance to magnetic fields, ensuring reliable accuracy in daily life. With its extended autonomy, the watch remains dependable even when left unworn for several days.
Clear, Well-Proportioned Design The 42mm stainless-steel case measures 11.44 mm in thickness, offering a slim yet substantial wrist presence. Diamond-polished hour markers and luminous sword-style hands ensure clarity against the vibrant blue dial. A sapphire crystal with anti-reflective coating provides both durability and excellent legibility in varied lighting conditions.
Crafted for Everyday Wear A brushed and polished stainless-steel bracelet secures the watch with a folding clasp, combining comfort with lasting strength. The exhibition case back highlights the refined decoration of the movement, reinforcing its mechanical charm. With water resistance to 50 metres, the Jazzmaster is ready for everyday wear, from work to leisure.
A Harmonious, Open-Hearted Icon The Jazzmaster Open Heart Auto H32705142 embodies Hamilton’s ability to merge timeless elegance with modern detail. Its open-heart design celebrates both precision engineering and aesthetic beauty, making it an ideal choice for those who value sophistication with a contemporary twist.
