I’m offering a rare King Seiko 4502-7001 in Mint to Unused condition. The 45KS is highly coveted by vintage King Seiko collectors, and it’s easy to see why. Powered by a high-frequency movement beating at 36,000 beats per hour, the accuracy of this watch is outstanding—surpassing even that of my modern Grand Seiko models. This 45KS has been a standout piece in my collection for several years. The dial, crystal, case, medallion, and buckle are all in impeccable condition. The only component that wasn’t perfect when I acquired it was the strap, which I’ve replaced with one that closely matches the original design. I purchased this watch in Japan during a conference and have since kept it carefully stored in my watch box. Given how rarely I’ve worn it, I’ve decided to list it for sale in the hope that someone else will appreciate its beauty and craftsmanship as much as I have. I’m asking $1,400, which includes shipping and insurance. The time stamp is in the last photo.
The price of this watch is an outlier for this particular model and not included in the distribution. It may be miscategorized, incorrectly priced, or extremely unique.
Estimated Private Party Value $600 — $790
