Gentleman Open Heart

The Tissot Gentleman Open Heart brings a contemporary twist to Swiss watchmaking, showcasing its automatic movement through a striking aperture at 12 o’clock. This model is positioned as a dressy daily-wear alternative within the Gentleman lineup, offering a glimpse of the Powermatic 80.601 caliber—a movement prized for its 80-hour power reserve and silicon balance spring, which enhances both accuracy and magnetic resistance. The open-heart design isn’t just aesthetic; it’s a nod to mechanical transparency and modern watchmaking innovation.

Reference numbers for the Gentleman Open Heart series include options like the T127.407.11.041.00 (blue dial, steel bracelet) and T127.407.16.041.00 (blue dial, leather strap). Variants differ mainly by dial color and strap material, with blue and silver dials being the most sought-after. Expect prices to vary based on condition, original box and papers, and whether the watch comes on its factory bracelet or leather strap—bracelet versions often command a premium on the secondary market.

This 40mm model wears well across wrist sizes, balancing a classic silhouette with contemporary flair. Water resistance is rated at 50 meters, enough for everyday splashes but not for swimming. When shopping, prioritize examples with minimal case wear and a clean exhibition caseback, as scratches here can detract from the visual appeal of the open-heart movement. The Gentleman Open Heart is ideal for those seeking a Swiss-made automatic with a modern edge and proven reliability.
