# Yoshiaki's SEIKO Obsession This is the third generation Baby Tuna series, featuring the short-lived outer shroud protector. The Frankenstein Monster I'm also offering is quite impressive, but this one boasts a stunning form and a commanding presence. It is considered the successor to the SRP637K. The outer shroud protector is made of thick ceramic. It was produced inheriting the exterior form of the 50th Anniversary Special Edition models SRP653 and 655. It's extremely rare, as it's rarely seen. It functions without issue for daily use. Although it's a large size at approximately 52mm, the curved shape of the case back is designed for a surprisingly comfortable fit on the wrist.
