Truth told, I picked up this spiffy King Seiko 4402-8000 from 1966 a few weeks ago. It's just back from the spa where it received a full takedown service, and had a NOS crystal (I sourced) installed. No polishing - ever. The lugs are razor edged and the hands and markers really pop with the 'Zaratsu' polishing technique. Dial is pretty great too.
Crown and caseback are correct, with the 1966 having the (rarer) King Seiko shield design. Currently running at +3 seconds / day with a strong amplitude, also I am extremely pleased with the work of a new (to me) watchmaker. PM me if anyone is looking to have work done on a vintage Seiko (King, Grand, etc.) he shows the proper care =).
Icing on the cake: its new Crown & Buckle (Black Label) navy strap arrived 35 minutes after pick-up! Just really (really) pleased with how awesome this 51-year-old watch is...
