Grand Seiko Automatic GMT SBGM247 shipped from Japan!

Grand Seiko SBGM247 is a representative Grand Seiko GMT watch that combines practicality and beauty.

In order to enable accurate and quick reading of the time in a variety of situations, the watch features thicker and easier-to-read hour and minute hands and indexes, and even the second hand and GMT hand have been designed to be easily distinguishable from each other to achieve a perfect balance in design and high legibility.

The calm green dial, which creates a variety of expressions like the wilderness, is another distinctive feature, combining practicality and beauty.

In addition, the compact case size of 40.5 mm and the reinforced water resistance of 20 atmospheres fully meet the requirements of a sports watch.

Grand Seiko, born with the aspiration of "creating the world's best wristwatch," continues to pursue mechanical watches with even higher precision.

The 9S Mechanical is a unique watch made by a manufacturer that combines the latest technology with the skills of a master watchmaker, so that you can experience the high precision of the 9S Mechanical as you use it.

The precision of a mechanical watch, which is composed of 200 to 300 parts, greatly affects the accuracy of the movement. In order to maximize the machining accuracy of the parts, we use the advanced technology of MEMS (Micro Electro Mechanical Systems) in the manufacture of the escapement.

However, simply assembling any parts as they are will not achieve the precision that is appropriate for a Grand Seiko.

It is only through the manual labor of craftsmen with a thorough knowledge of the mechanics of mechanical watches and superior skills, who search for the optimum combination of parts and adjust them in 1/100 mm increments, and then carefully assemble them that the 9S Mechanical begins to tick with the precision that only a 9S Mechanical can achieve.

• Drive System: Automatic (with manual winding)
• Duration: Approx. 72 hours (approx. 3 days) at maximum winding

Accuracy based on Grand Seiko's own standards, measured under the conditions of 6 posture differences and 3 temperature differences with the movement alone before shipment from the factory.
It differs from the accuracy (portable accuracy) under the environment in which the watch is actually used by the customer.
Also, due to the characteristics of mechanical models, depending on the conditions of use (carrying time, temperature, arm movements, strong shocks or vibrations), the aforementioned accuracy range may be exceeded.
