# Yoshiaki's SEIKO Obsession This is the third generation Baby Tuna series, featuring the short-lived outer shroud protector. While the Frankenstein Monster is also quite impressive, this model boasts a stunning form and outstanding presence. Also known as the Armored Monster, 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 is extremely rare, as it is rarely seen on the market. It functions perfectly for daily use. Although it is a large size at approximately 52mm, the curved design of the case back allows it to surprisingly fit the wrist well.
