IWC Mark XX - black dial - bracelet - full set purchased 3/7/2023 $4600 shipped (CONUS). add 3.5% for PP G&S. Excellent condition. Detailed photos with studio lighting show everything, on the wrist this looks like new. I'm not a watch reseller, just a hobbyist-photographer who enjoys experiencing watches. The accuracy on this particular example is insane... as an experiment I fully wound it and synced it with my radio control quartz Citizen Skyhawk, then left both alone in my watch box for days. It stayed right on through the entire power reserve! Never seen a mechanical watch like this. I took pics with my phone through the "experiment" if you want to see. I saw a great opportunity and snatched up another watch and sadly I am in no position to keep both. Watch is covered by IWC warranty as well as warranty from Topper Jewelers (where I purchased it).
