THE JAPANESE EXCELLENCE

It is on a perfectly polished surface that the play of shadows and light is best expressed, creating a subtle harmony. An interaction that is found in the traditional Japanese sliding door Shoji, in the translucency of the screens, in the finesse of the Japanese fans.

 

 

MECHANICAL HI-BEAT 36000 GMT CALIBER 9S86

 

This high-specification movement delivers the same accuracy (-5 to +3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveller needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The GMT hand shows the time in the home time zone.

 

Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the second hand so that the highly accurate timekeeping delivered by the Hi-Beat 36000 is not lost. Calibre 9S86 is the embodiment of the Grand Seiko ideal of high accuracy, maintaining exceptional precision in both the essential time display and the GMT function.

 

 

 ABOUT THE BASE CALIBER 9S85

 

In Seiko's 10 beat movement, the balance wheel that controls the accuracy of the mechanical watch oscillates 10 times per second. This is equivalent to 36,000 oscillations per hour, which earns it the name "Hi-Beat 36000". Ordinary movements beat at a rate of 21,600 oscillations per hour (6 per second) or at 28,000 per hour (8 per second). You can clearly tell that the 10 beat movement has a higher number of beats per unit of time.

 

Grand Seiko's challenge to re-introduce the legacy of the 10 beat movement gave rise to Caliber 9S85, the first movement of its kind in 41 years. The redesigned hairspring and mainspring complement cutting-edge MEMS technology to raise precision and reduce component weight, simultaneously improving durability and securing the torque necessary to maintain a rate of 36,000 oscillations per hour. The movement is practical and reliable, with a maximum power reserve of about 55 hours.

 

 

WHAT MAKES DE 9S CALIBER SPECIAL

 

The concept of Grand Seiko was born from the desire to build the world's best watch, and the collection continues to push precision in mechanical watches to the limits of timekeeping technology.

 

As a true manufacturer, Grand Seiko incorporates the latest technology alongside its breadth of craftsmanship to raise the art of watchmaking to its peak.

 

With anywhere between 200 and 300 individual parts, mechanical watches must exhibit a near-perfect consistency of functionality in the detail of these parts to ensure the precision of the movement. Seiko employs Micro Electro Mechanical Systems (MEMS) technology in the manufacturing of its escapements, bringing the mechanical accuracy of its parts to the forefront of technology.

Mere parts alone, however, cannot constitute the level of precision for which Grand Seiko is renowned.

 

The task of assembling Grand Seiko is born by craftsmen and women who have honed their craft to such an extent that they can adjust parts by hand to tolerances of one-hundredth of a millimetre. This extremely detailed craftsmanship is what has made possible the very precise timekeeping delivered by the 9S mechanical movement.
