On sale today is a pretty rare watch, reference ck859 in a large 35mm scarab case. As It is a scarab case design, it wears even larger than a regular datejust at 36mm. Unknown service history but the caliber 26.5SOB works great and keeps good time. Looks extremely clean as well. Asking at USD 5k shipped to your doorstep, using Fedex worldwide. Any questions, please email me at reficul_x AT yahoo.com many thanks for watching this space.
