Spring Drive GMT with a classic appearance and innovative heart
This model features a Spring Drive, the third movement mechanism, combining the motive force of a mainspring found in mechanical watches with the high precision of a quartz watch, as well as a GMT indicator, all incorporated into a classic design.
The motion of the second hand, smoothly gliding over the black dial, is enabled by the watch’s exclusive sweeping mechanism. This motion is different from that of either a mechanical watch or a quartz watch.
By placing a simple 24-hour scale inside the classical rail track scale, we designed the watch to maintain a formal style with an additional feature of a GMT indicator.
To underscore the texture of the material, a white-plated hand that stands out against the black dial is used for the 24-hour hand. This adds a sophisticated taste and high visibility to the watch.
