Grand Seiko 45GS 45KS See-through case back Grand Seiko
It was made to order at a machine factory with particular attention to its shape to match the Seiko style.
Compared to the old model, the opening has been made smaller to hide the movement holder and presser foot, resulting in a more beautiful finish.
The material is SUS stainless steel, and the thickness excluding the screw part is 1.2 mm, the same thickness as the genuine case back including the medallion.
The skeleton part uses sapphire crystal for windshields and is bonded with Seiko genuine glass adhesive compatible with 10 atmospheres.
Screwing into the main case is very smooth.
