That’s because Grand Seiko adds the ceramic Swiss Replica Watches case as an “outer case” that is wrapped over a lightweight titanium inner case Replica Watches that actually encapsulates the movement itself. Because the movement’s size is given and the titanium inner case has to have its dimensions as well so that the movement can be fixed to it on the inside and the ceramic on the outside, Hublot Replica the finished watch ends up considerably larger than it
