The Tissot Gentleman Open Heart T127.407.11.031.01 combines a bright silver dial with warm rose-gold-tone details and a captivating view of its mechanical movement. The open-heart aperture reveals the regulating mechanism in continuous motion, introducing visual depth without sacrificing the Gentleman collection’s clean and versatile character.

Rose-gold-tone hands and applied indexes stand out against the silver dial, creating an elegant contrast that distinguishes this variation from the cooler rhodium edition. Super-LumiNova® on the hands improves readability as surrounding light fades, while the carefully balanced dial remains refined enough for professional settings and special occasions.

Power comes from Tissot’s Swiss Powermatic 80 automatic movement, which stores energy through the natural motion of the wrist. When fully wound, it provides up to 80 hours of power reserve—enough to continue running for more than three days without being worn. Its patented Nivachron™ balance spring provides improved resistance to magnetic fields generated by many everyday electronic devices, supporting dependable mechanical performance.

The 40 mm stainless-steel case measures 11.50 mm thick and combines polished and brushed surfaces for a sophisticated contemporary finish. Scratch-resistant sapphire crystal with an anti-reflective treatment on the underside protects the dial, while a transparent caseback provides another view of the automatic movement and its operating components.

A stainless-steel bracelet completes the design with a butterfly clasp operated by push-buttons. Its interchangeable quick-release construction permits compatible bracelets or straps to be fitted without specialized tools. Water resistance to 100 metres adds practical durability for everyday wear and recreational swimming.

With its warm dial accents, exposed mechanics and extended autonomy, this Gentleman Open Heart offers a distinctive balance of traditional Swiss watchmaking and modern versatility.

An expressive Swiss automatic that reveals its mechanical character from both sides.
