Baselworld 2019 / Grand Seiko Sports Collection Spring Drive 20th Anniversary Limited Edition Model SBGC230

　This Spring Drive 20th anniversary model is part of the Grand Seiko Sports Collection. The newly adopted case design, which combines square and round shapes, is inspired by the brand's iconic lion. To improve comfort, the center of gravity has been lowered and the contact area with the wrist has been increased, resulting in a flatter shape. However, the lugs have been carved out of one piece and then made multifaceted, with Zaratsu polishing and a satin finish, giving the case a three-dimensional appearance.
