Beautiful 2013 Constantine Weisz skeletonized tourbillon with day night indicator, 72 hour power reserve and 24 hour time. Case measures 45 mm and the band is 22mm alligator. This has been in my collection for many years. I’ve never worn it but I’ve tried it on and I’ve wound it every two months or so. And is keeping time very well. This item is in showroom condition very fine. Box and papers included. Please email with any questions. And all reasonable offers welcome.
