Rolex Day-Date 1803 with COSC Papers

The Rolex Day-Date reference 1803 dates to circa 1967 and includes its chronometer certificate (a.k.a. "COSC papers") and an extremely rare "The Day-Date" promotional booklet. The dial is beautifully preserved and the case is crisp and full. I purchased this watch from Heritage Auctions in April for $8,437.50, just so there is full transparency on its origin and what I paid. I understand that the consignor to the auction was the original owner. I paid over $1,000 for a service by an excellent watchmaker recently, as well, so it is ready for the next owner.
