A new era of Spring Drive GMT with a ceramic bezel.
This model is equipped with a GMT display function in the Spring Drive mechanism, which provides high accuracy, equivalent to the accuracy of a quartz watch. The second hand of a wristwatch equipped with Spring Drive does not "count" the time, but continues to move smoothly along the dial .
The 4 o'clock crown is designed with volume and practicality in mind and does not interfere with the smooth movement of the wrist, even during active activities.
