No kidding regards the box - here is an example at $1,228.50 (in excellent condition) - http://www.ebay.co.uk/itm/Heuer-Monaco-Box-EXTREMLY-RARE-70s-/390829438547?pt=Wristwatches&hash=item5aff3ff653&nma=true&si=AKeMmOFeqwZoZFfnPuw6jvczWhY%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
Removing the bracelet will require some skill and the correct tool. Best to take it to a watchmaker to remve, take some pictures and then get him/her to replace it. The serial is most likely at the 12 end and the model number at the 6. If you take it to a watchmaker then they could remove the back but make sure they have the correct bench tool and not the hand type which are likely to slip and scratch the back case.
