【貴朵8L75】拆解精工體系中最能打的機芯，如今是GS和貴朵的標配！

Hello everyone welcome to this episode of Wanbiao ICU Today we are going to take apart another Seiko Grand Seiko Unlike the previous Grand Seiko this one is different This watch uses the 4S77 movement while this one uses the 8L75 movement because a watch enthusiast from Shanghai sent it over for maintenance This watch was a limited edition released by Guo Duo in 2004 as part of the Pacific series Only 300 pieces were made worldwide Although its movement is relatively basic But I personally think it's still worth sharing with everyone The establishment of Guidou was actually to separate an independent high-end sub-brand from Seiko Early on it was mainly gold and platinum models Its market was also mainly focused on Japan Unlike GS it was not as international This brand had a high starting point But in the past it did indeed have a period Fallen to producing cheap watches So now we see some cheap second-hand Guo Duo quartz watches in the market There's nothing surprising about it because it does have a certain history After 2000 after the introduction of the SpringDrive and 9S movements Grand Seiko finally found its identity again The highest standard of Seiko's basic movement is the 9S series introduced in 1998 The current Seiko high-end watch series and GS models all use the 9S series movement This Bio movement is actually the high-end version of the 9S Although there are slight differences in the base plating and finishing of the movement But the structures of the two movements are exactly the same We can take a look at them in a moment
