For sale is a vintage King Seiko, reference number 4502-7001. This particular KS model is rich in history, and is powered by one of the most significant movements Seiko has ever put in its watches. Please watch this video for an excellent introduction of the movement as well as the watch:

Specs on the watch are as follows:

  • Case width: 36mm (w/o crown)
  • Lug to lug length: 42mm
  • Lug spacing: 18mm
  • Thickness: 9.8mm
  • Crystal: hardlex
  • Movement: Seiko 4502 high beat hacking movement

The 36,000 bph hand-wind movement is running well and very accurate. I don't know the service history of this vintage watch, but it's keeping time within 3 seconds a day when laying flat. I measured the power reserve to be a healthy 40+ hours.

The case design is the pinnacle of Seiko language in my opinion. You can see where the modern Grand Seikos get their signature case shape. This particular sample appears to have never been polished, retaining the sharp lines along the edges. As you'd expect for a watch of this vintage, there is a good amount of fine scratches on the surface of the case. Also obvious from the pictures is that the crystal is far from perfect, with the damage along the crown side beveled edge the most noticeable. I believe replacement crystals can be sourced, but I've never felt the need to.

All things considered, this watch is in very good cosmetic shape considering its age, and I've accounted for its cosmetic condition in the pricing. The golden medallion on the case back is fully intact and in wonderful condition.

The watch is on a brand new Shell Cordovan leather strap (first and last picture). The strap that came with the watch will also be included. Though it appears period correct, it is not the original OEM strap. No box or papers for this watch.
