Gentleman Open Heart 40mm T1274071103101

The Tissot Gentleman Powermatic Open Heart is an elegant watch, featuring a new and contemporary open heart design. Its strong curved horns are an harmonious continuation of the watch, favoring a pleasant wear around the wrist. This eye-catching design is a symbol for swiss made watchmaking tradition, and is a strong visual reminder of Tissot’s heritage due to the beauty of the movement beneath it. Ensuring visibility under all conditions is an important goal for Tissot. This is why some timepieces feature a material we call SuperLuminova®. This material is placed on visible parts such as dials and hands, where it functions as a miniature accumulator of reflected light when the watch finds itself in the dark*.
