Grand Seiko only can make dress watches but come to sport watches grand Seiko cannot design a smaller and thinner case like rolex Daytona,for me rolex Daytona is king of the chronograph,I found rolex Daytona is a perfect design from movement to case and bracelet and even the size is 40mm case so slim also bracelet is from 20mm to 16mm.I personally opinion grand Seiko is too big and thick bracelet also not nice.
The face of GS is quite nice I won’t deny but it is big and you need to at least have a 17.5 cm wrist to look nice wearing it. Another thing is that the clasp of GS don’t look nice and grand. I went to the shop to try it on, it look nice and fixed my 18cm wrist size but the price is too high.
