Case and Crystal The 37mm stainless steel case features a strong, purposeful design characterized by robust, angular lugs with distinct facets and a smooth, polished bezel. A signature element of this era is the recessed crown positioned at four o'clock, creating a streamlined look, complemented by a dedicated pusher at three o'clock for the date function. The case back is a clean, polished snap-on style featuring the engraved serial number, while the interior is correctly stamped with the Suwa Seikosha logo and reference details. The watch is fitted with a domed acrylic crystal that provides a warm, vintage distortion to the dial edge and remains clear and highly legible. The case exhibits honest, light vintage wear, with superficial micro-scratches consistent with careful handling over the decades, while retaining its original structural integrity and charm. Movement Powering this timepiece is a robust Seiko 23-jewel automatic movement, a hallmark of the Sportsmatic Deluxe line. The movement presents beautifully in the macro photography, featuring clean industrial finishing and a distinctive rotor engraved with red text reading Seiko Sportsmatic 23 Jewels.

Condition This timepiece is presented in excellent vintage condition. The case remains strong and well-defined, showing only normal signs of careful use.
