Story of This Watch: The Diamond Quarters variants were highly popular in Asian & Middle Eastern markets during the late 1970s & 1980s as statements of accessible luxury. This is Seiko 5 engineering meeting late-disco executive styling - rugged tool-watch DNA packaged as a jewelry piece. The faceted diamond markers genuinely catch light on the wrist, & the black dial makes them pop brilliantly. The 6309 movement is entirely metal gears, making it incredibly easy to service & maintain for another forty years.
