Spring Drive Movement

At the heart of the Grand Seiko Spring Drive Chronograph GMT lies its impressive Spring Drive movement. This innovative mechanism combines the best of both mechanical and quartz technology, resulting in a watch that offers unparalleled precision and reliability.

The Spring Drive movement utilizes a unidirectional governing wheel, which controls the flow of energy throughout the watch. This wheel ensures that the watch always maintains a constant force, allowing for extremely accurate timekeeping. Additionally, the use of quartz feedback ensures that the timekeeping remains precise, with an accuracy of +/- 15 seconds per month.

One of the unique features of the Spring Drive movement is its ability to harness the potential energy of the mainspring. This energy is then used to power the watch, resulting in a three-day power reserve. This impressive power reserve ensures that the watch will continue to operate accurately even if it is not worn for a few days.

The Spring Drive movement also offers other practical benefits, such as independently settable local hour hand and hacking seconds for synchronization. These features make it incredibly convenient for travelers who frequently switch time zones or for those who require precise timekeeping in their daily activities.

Furthermore, the Spring Drive movement is designed to be robust and reliable. The fixed and stable crown ensures that there is no accidental movement or damage to the watch. This, coupled with the smooth and precise chronograph action, guarantees that the watch will perform flawlessly in any situation.

At 16.3mm in thickness, the watch has a substantial presence. However, this thickness is necessary to accommodate the impressive Spring Drive movement and its three-day power reserve. Despite its thickness, the watch remains comfortable and will not feel overly bulky or heavy on the wrist.

The double-stepped case with a conical bezel is another design element that enhances the wearability of the watch.

The power reserve indicator on the dial provides a visual indication of the remaining power, allowing you to plan accordingly.

The Spring Drive Chronograph GMT boasts a water resistance rating of 100 meters, making it suitable for everyday wear and light water activities. While it is not intended for diving or prolonged exposure to water, this water resistance rating ensures that the watch can withstand the occasional splash or shower without any damage.
