I'm no expert market watcher by any means, just a 1133G owner and mild obsessive (so hardly impartial then!) but I don't doubt the Monaco's long term prospects. Ultimately it's the Heuer that most truly qualifies as 'wearable art', an iconic design that's striking to both view and handle, with the bonus of a historically important movement and very limited numbers on the market at any particular time, relatively speaking (if there were less than 5,000 of all versions new, how many survive now?) And of course movie associations that are easy to sneer at (I certainly find myself doing it) but as long as TAGH has cash to spare, presumably we'll keep seeing media images here and there which will keep it hovering in the wider public's consciousness, drawing the interest of future generations of fledgling watch enthusiasts back in time to the striking original. Various Heuers have had and will have their moment in the sun and even those with more enduring appeal will no doubt fluctuate in line with tastes and fashions but I'd venture to suggest that the Monaco is a solid investment in the long term. Especially in grey with sunken grey subs, the ultimate dial in my view which repays any number of viewings!

The ebay piece clearly has a pretty big seal issue and most examples I see on ebay and chrono24 etc seem to have sizeable question marks so I'd imagine it's difficult to gauge the value of decent original pieces. Presumably as time passes and the ever-shrinking number of decent examples continue to find their way into the hands of collectors who'll generally hold on to them, our view of prevailing values will be ever-more vulnerable to distortion by the lesser pieces with dial issues remaining in circulation visibly for longer periods due to the reluctance of increasingly educated buyers (thanks to communities such as this and the internet generally) to bid on them?
