You have to understand that it is not just a classic of the plastic-digital watchmaker's art, circa mid 1980's. It is also a celebrity souvenir, clearly visible in one of the official photographs of the great author. Such a memento, together with a copy of the photograph would cause intense excitement at a collector's meet on the Planet Borscht. So make your offer appropriately ridiculous. (For an additional $7,000, I will throw in a 1985 Mercedes-Benz Turbodiesel station wagon in pretty darn good mechanical condition...goes nicely with the nerd watch. The Earth Shoes are gone, or I could include them, making a perfect set).
