This is a beautiful Swiss made watch that I just had serviced, and cleaned and of course new battery. I do not have the original box, or much knowledge of the watch, but I see them on Ebay for $7500 (new). My Jeweler says it's authentic and to sell it for the going price but I really need to find the person that knows what they are looking at and know it's a deal! I also had a new leather band put on it. It is gold plated over stainless steel. No scratches on face or any show of wear. It's a mans watch but a woman could wear it if she likes the bigger watches. It has 3 registers with date window. Also it is water resistant. The #'s on the back have an x over the top of them; then it says 237-406. I am motivated to sell! I'm lowering the price from $2100 to $1775! Now I have lowered it even more. Make me an offer!
