# Yoshiaki's SEIKO Obsession This is a Professional Diver 300m, first released in 1991. This model follows the design of the 75 series 300m diver while upgrading the movement. The movement is equipped with the high-performance caliber 【7C46】. It has excellent magnetic resistance and is a highly reliable movement with high output torque that allows for thick hands, despite being quartz. It is highly practical, featuring a quick-set date and day function, as well as a hacking seconds function. The exterior features a saturation diving specification that employs the "outer case protector" which boasts the robustness of Seiko divers' watches. (Water resistance is not guaranteed due to being USED) The glass uses a domed dual-curve glass. The hands and indexes have luminous paint. The crown is set at the 4 o'clock position. Despite the large case, it is designed not to hinder wrist movement, making it highly practical. The day display can be switched between Japanese and English, allowing you to use your preferred language. The rotating bezel (anti-reverse rotation type, rotates counterclockwise) rotates with a moderate click feel. The screwing of the screw-down crown is also good. When screwing in the crown, to avoid damaging the threads, it is recommended to carefully find the point where it can be screwed in and screw it in slowly. From hand winding to quick-setting and switching of the calendar to tightening the crown on the anti-reverse bezel, everything has been confirmed to be working. The watch stand is for photography purposes and is not included. There are no noticeable scratches, but there are extremely fine hairline scratches on the crystal that do not appear in the photos. Although it is a very clean product, it is not new, so there may be scratches or scuffs that do not appear in the images. Please make your judgment from the images and be sure to understand and agree before purchasing.
