This is a used item. Grand Seiko 62GS Seiko Matic Chronometer Exhibition Caseback Caseback 6245-9000 6246-9000 Grand Seiko Seiko GS 45gsfan This is a Japanese-made see-through case back that uses sapphire crystal and is compatible with the 6245 and 6246 series Grand Seiko and Seikomatic chronometers.Not only can you use it while watching the operation of the movement, but I also recommend it to those who are concerned about markings such as labor commemorative stamps on the back cover.Also, by storing the original case back, you can prevent the medallion from deteriorating or peeling off.*This product is for sale as a back cover.The image of the watch body is an installation image.■About the product■This item was made to order at a machine factory with particular attention to its shape to match the Seiko style.We were very particular about the size of the opening to optimize the appearance of the movement.The material is SUS stainless steel and the thickness excluding the screw part is 2.4mm.The thickness is the same as the genuine camera back without the medallion, so you can use it without any discomfort.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.■Supported cases■6245-90006245-90016246-90006246-90016216-9000Thank you for your understanding as we strive to conduct transactions quickly.Grand seiko Display Caseback
