The Hamilton Jazzmaster Open Heart Auto H32705131 balances tradition and innovation with a 42 mm stainless steel case and a striking black open-heart dial that reveals the Swiss H-10 automatic movement. Protected by a sapphire crystal and offering an exhibition case back, this watch delivers an 80-hour power reserve and 5 bar (50 m) water resistance — a refined choice for those who appreciate both design and horological performance.
