About Grand Seiko SBGE245

Grand Seiko Sport Collection

A Spring Drive GMT Limited Edition

Proving that high-performance timekeeping can be incredibly stylish, the Grand Seiko Sport collection will allow you to enjoy expert precision and striking aesthetics.

This Grand Seiko Sport watch sits confidently in a 44mm stainless steel case, protected by sapphire crystal glass.

Reminiscent of the lavish wooden decking of a luxury cruise ship, the mahogany red dial showcases a date display window, a 24-hour hand, a power reserve display and a stop seconds function.

A rotating bezel with 24-hour notation allows for the simultaneous indication of three different time zones, while a screw down crown and a powerful Spring Drive movement further enhance the functionality of this timepiece.

Water resistant to a remarkable 200 meters and offering a 72-hour power reserve, this model fastens with a polished stainless steel bracelet with a secure three-fold clasp.

Limited Edition of 600 pieces.

 

About Spring Drive

Spring Drive is Seiko’s exclusive movement that achieves an unprecedented level of accuracy (+/- 15 seconds per month on average, equivalent to +/- 1 second per day) by regulating a spring-driven watch with state-of-the-art electronic technology that functions without batteries or other external power source.

As in conventional mechanical watches, the sole power source of Spring Drive is a mainspring that can be wound by the motion of an oscillating weight or by winding the crown. And just as in mechanical watches, the mainspring drives a series of gears that rotate the hour, minute and second hands. A rotor, connected to the end of these gears, generate a small electrical charge that activates an electronic circuit and quartz oscillator.

The Tri-synchro regulator is a unique speed controller for Spring Drive that replaces the escapement, which is a mechanical speed control device used in almost all conventional mechanical watches. The Tri-synchro regulator moves the second hand in a smooth motion, without ticking and with extreme accuracy.

Some 80% of the components in a Spring Drive caliber are the same as those in a luxury mechanical watch. Spring Drive is a movement powered by a spring, just like a mechanical watch, with a different kind of regulator and combines the long-lasting autonomy of a mechanical watch with the precision that, until now, only electronic watches could provide.

To ensure reliable and accurate operation, all these parts need to be manufactured to the highest standards of precision, and assembling them requires superior craftsmanship.

The development of the Spring Drive movement caliber 9R was made possible because Seiko is one of the very few manufactures with expertise in both mechanical and quartz watches.

Since the first Grand Seiko Spring Drive in 2004, new movements have been created with even more complex mechanisms–including the GMT in 2005 and chronograph with GMT in 2007. Showing that with the Spring Drive caliber 9R, time never loses momentum.

Grand Seiko SBGE245 History :

Prior to 1960, to challenge the status of Swiss watches and change the perception of Japanese watches, Daini Seikosha and Suwa began the discussion of a product line that can match the quality of Swiss watches under the suggestion of the parent company. At the time, Suwa Seikosha Co. was in charge of manufacturing men’s watches, so it was decided that Suwa would be producing the first Grand Seiko (GS).

The first Grand Seiko was released in 1960, it was based on Seiko’s previous high-end watch, CROWN. This Grand Seiko has a 25-jewel, manual-winding, 3180 caliber, and only 36,000 units were produced. This was also the first chronometer-grade watch manufactured in Japan, and it was based on Seiko’s own chronometer standard.

Design style

The design language of the Grand Seiko was set in 1967, with the creation of Grand Seiko 44GS. The 44GS set the ground for all future Grand Seiko with nine elements. These elements help improve the legibility of the watch under different situations, and create a sharp, crisp visual impression:

  1. Double width index at 12 o’clock
  2. Multi-faceted rectangular markers
  3. Highly polished bezel
  4. Highly polished planes and two-dimensional surface
  5. Half recessed crown
  6. Flat dial
  7. Multi-faceted hour and minute hands
  8. Curved side line
  9. Reverse slanted bezel wall and case side
  10. Dress style with simple but beautiful design
  11. Zaratsu polishing

CONCEPT

Grand Seiko SBGE245 Concept

A new Spring Drive Limited Edition enriches the Grand Seiko Sport Collection. In every aspect, from the movement to the case, this new GMT watch has been created for life on the open ocean. With 20 bar water resistance, enhanced shock resistance, a special Spring Drive caliber that has been adjusted for greater resistance to temperature change, the watch is built to withstand everything that the sea can throw at it. Even the position of the crown adds a new level of security; set into the case at the four o’clock position, the risk of it being knocked or damaged is minimized.

 

DESIGNGrand Seiko SBGE245 Design

The rotating bezel has 24-hour markers which, when used in conjunction with the GMT hand, allow the watch to indicate three different time zones at the same time, making the watch perfect for international travel on the sea or, indeed, in the air.

 

Grand Seiko SBGE245 Design

The dial has a subtle sunburst pattern and a deep, rich color, as if made from the polished mahogany of a yacht’s decking.

 

Grand Seiko SBGE245 Design

This limited edition is presented on a steel bracelet with a double safety clasp. In addition, it comes with a strap made of reinforced silicon which has the strength needed for use on deck and yet is still flexible and comfortable on the wrist. The Grand Seiko lion is imprinted boldly on the strap’s retainer.

The lion emblem also adorns the case back, alongside the individual serial number (No. 001/600 to No. 600/600) of the watch.

AUTOMATIC SPRING DRIVE 3-DAY GMT
Caliber 9R66

In 2006, just two years after the completion of Caliber 9R65, Grand Seiko’s first 9R Spring Drive movement with GMT function, the Caliber 9R66, was unveiled.

“GMT” stands for Greenwich Mean Time, and uses a 24-hour hand (GMT hand) as the fourth hand on the watch dial in addition to the hour, minute and second hands.
