It is a model that has a classic design with a GMT display function on the third mechanism "Spring Drive" that enables high precision equivalent to a quartz watch while using the mainspring used for mechanical watches as a power source.
The movement of the second hand, which differs from mechanical and quartz movements, is the sweeping movement that smoothly flows over the white dial.
By laying out a simple 24-hour scale inside the classical railway scale, the GMT function display was added without breaking the formal expression.
The 24-hour hand, which takes advantage of the texture of the material, uses blue steel hands that shine on the silver dial, achieving both high-quality taste and visibility.
