That is easily worth $2000. probably more if the movement has no damage, and just needs a service. look at the recent prices of 105.003's And subtract the price of a full service, replacing pushers and crystal, and you have your value. then subtract $0 - 1500 as your guess as to the state of the movement. Therein lies the gamble. but I would say right now in eBay that would fetch at Least $3000, because some one will take the chance.
It's the lure of potential that gets bidders hot. This example plus the cost of restoration will exceed the cost of a restored example in the same condition. It's the law. You could look it up!
