Condition
Pre-owned with visible wear from normal use. The case, bezel, crystal, bracelet and clasp show scratches, scuffs and surface marks. The bezel retains its distinctive contrasting red and black markings.
The bracelet and clasp are Seiko-signed. I have not verified the bracelet’s exact factory part number, so I am not representing it as the watch’s original factory bracelet.
Please review all photographs carefully for cosmetic condition and exactly what is included.
Functionality
We still need to insert your actual testing here. I won’t claim that the day/date, timekeeping or other functions have been tested until you confirm them.
