Spring Drive GMT with an innovative heart in a classic look. It is a model with a classic design, equipped with a GMT display function on the third mechanism “Spring Drive” that enables high accuracy equivalent to that of quartz watches while using the mainspring used for mechanical watches as a power source. The movement of the second hand, which is different from the mechanical and quartz movements created by the original mechanism, is a sweeping hand movement that flows smoothly over the white dial. By laying out a simple 24-hour scale inside the classical railway scale, a GMT function display has been added without breaking the formal look. The 24-hour hand, which takes advantage of the texture of the material, uses a blue steel hand that shines on the white dial, achieving both a high-quality taste and visibility.
