This little beauty is a rare find indeed....I bought it at the end of last year and can Guarantee authenticity and that it has never been worn or used. It comes with Original Box and papers. As much as you may think you have seen a watch like this, i can assure you that you have not - it does resemble other models, but this one is unique.the Caliber is 1866 As with all my items it is Guaranteed Authentic. I will post this at my expense, however on any watches i sell, income tax, VAT, Import duties etc etc are YOUR responsibility i am afraid i can not help there. The item will be tracked, registered and Insured and it MUST be signed for by you the buyer. Please feel free to make an offer or discuss this beautiful watch with me.
