SHE WILL LOVE IT!  An absolutely gorgeous, museum-quality piece that I'm simply afraid to wear because I don't want to ding it, and that's no fun.  Bracelet is factory tight. Finish appears to be the original factory finish with no defects, never having needed to be re-polished because the watch hasn't been worn. The bracelet at the AP logo on the clasp has no scratches or defects.  Estimated year of manufacture: 1996, before the rose gold craze hit, so AP made very few of these.  According to my 1995 AP price-list, the yellow gold 56175.BA retailed for US$23,000. Inside circumference is 160mm including all three removable links (each one 1/4-inch). Fits comfortably on my 6.25-inch wrist. Remove the three links to size this down to about 5.5 inches. Extra-extra thin: only 5.7mm. AP has nothing like this in their program today. AP makes similar models today that will set you back more than $30,000.  You can waltz-in and buy a new AP 67651 anytime if you have the money but you won't find a 56175OR. Certainly not in this condition. Personally, I think the 56175OR is a lot cleaner, classier and sleeker than the current AP models. Total weight 126 grams. Case & bracelet 18k (750) rose gold. Clasp is 18k (750) white gold, fully hallmarked. Screw-down crown. Watch works and reliably keeps time as quartz does. Hands & dial are obviously 20 years old so the luminescence fades pretty quickly upon exposure to UV light. Champagne (pale yellow) dial. You will see steel, yellow-gold, two-tone and tantalum 56175’s on the market all the time but rose gold is EXTREMELY RARE. No box or papers. I will accept PayPal for the complete amount in one PayPal transaction if PayPal allows it. However if PayPal does not, then cash or bank wire only in advance, for the full amount (it’s not allowed to split the payment for a single item into multiple PayPal transactions). I expect payment within the standard time limit, no extensions or exceptions. This watch is absolutely perfect and I stake my reputation on that, therefore no returns. It's too much trouble and I can't risk sending a pristine watch out and get a scratched watch back.

Official AP model number is 56175.OR.O.0789.OR.03.  IMPORTANT:  Bracelet is type 0789, which is the same bracelet as used on the 14790 series and the Nick Faldo edition.
