Grand Seiko 9F Quartz Movement Review

Grand Seiko 9F Quartz is no doubt, the most elegant and sophisticated movements that you can get your hands on. First developed in the year 1993, the competitors to this date are unable to replicate many of the special features of this 9F Quartz. Though Seiko is functionality plus affordability when it comes to its other collections, the Grand Seiko Collection is typically the perfect wristwatch with a 9F Quartz movement creating magic inside and making Grand Seiko a brand of its own.   


History of the Grand Seiko 9F Quartz

Let’s go back to the year 1963, the year Seiko released the first-ever quartz clock that was portable and could run on batteries that could last for the whole year. It was Crystal Chronometer QC-951. The watch consumed very little power and was accurate to around 0.2 seconds per day and almost 15 seconds per month which was amazing and radical at that time. From then onwards, in the year 1969, Seiko was able to release a quartz wall clock and then Seiko wristwatch with a quartz movement. The quartz wristwatch Seiko Astron was a revolution in the watch industry that provided time accurate to 5 seconds per month. 

Moving forward to the year 1993, when everyone has opted for the quartz movement, Seiko had to do something special for its quartz collection. That is where Seiko developed its Grand Seiko Collection with the 9F quartz movement. The single movement that was the best of all. 


Special Features of the Grand Seiko 9F Quartz Collection 

The Seiko brand, with its Grand Seiko sister, made its motto very clear that they wanted the best features of any quartz movement in a single timepiece. The Seiko made it happen with its 9F movement. 

The special features offered by the 9F Seiko Quartz are not replicated by any other brand to date. The most special feature is the “twin pulse motor control” of the 9F movement. This unique feature introduced by the Seiko gives its 9F movement the supreme mechanical excellence. The single tick of the 9F quartz is actually the distinct double movements underneath which increases the life of the battery up to three years and provides power to run the dauphine full-sized Seiko hands.  

Another special feature of the 9F quartz movement by Seiko is the sealed cabin. As compared to the many other high-end quartz timepieces that have several gaps to allow debris or dust to enter in the timepiece, the 9F features a specially sealed cabin which ensures zero contamination. That is why Grand Seiko enjoys its position for the world’s longest service interval. The sealed cabin enhances the lubrication in the timepiece for keeping it good to 50 years.  


Why 9F Quartz Movement is Better?

The watch lovers have set their eyes on the Grand Seiko 9F as it provides numerous advantages as compared to the other quartz movements 

  • The mechanism of anti-backlash in the 9F auto-adjusts with an addition of a regulatory wheel so that the second-hand hits each marker and make no vibration when the hand stops
  • The mechanism of the date change is extremely fast i.e. 1/2000th of a second. You are literally going to miss it if you will blink. 
  • The coil block of the Grand Seiko 9F is wound uniformly that ensures maximum efficiency as compared to the commonly used coil block 
  • 9F Quartz movement is super accurate. The accuracy ranges from 10 seconds a year to an extremely amazing 5 seconds per year while other quartz movements provide 15 seconds a month
  • The thermo-compensation mechanism in the 9F Quartz movement detect the temperature changes five hundred times in a day and then adjusts according to it that eliminates the effect of temperature on the movement
  • For the more precision and smooth mechanical running, the three hands in the Grand Seiko are made to move on the separate axis
