Inside Grand Seiko With the evolution of the spring drive movement. This is a short video from Hodinkee where they took a trip to the Seiko factory and see how the spring drive is made. The Grand Seiko range is the high end models of Seiko, ranging from £3,000 to £20,000, there is plenty of Grand Seiko lovers and more than likely they are great innovated watches just never got them unfortunately. I just always felt the Brand is lower end of the market but it seems not as the Seiko followings is huge! I will always be Rolex chap through and through was my first love.
