Up for sale is my vintage Sinn 101A - an extraordinary and very rare 39mm Sinn chronograph with a reverse-panda dial, Valjoux 7733, and large, screw-down crown. Details: * Sinn 101A * Stainless Steel case * Valjoux 7733, 17 jewels * Large, screw down crown * Rotating minutes track bezel * 39mm diameter * 19mm lugs, shipped on a new Monstraps leather strap The watch was just serviced. The crown and tube have were replaced in service, as the originals were stripped and would no longer screw down. The originals are in my possession and will be shipped with the watch. The new crown took quite a while to source and retains the original's size and significance. Please note, while the crystal has some small scratches and dust in the pictures, the dial itself is nearly flawless. Asking $5250 shipped CONUS. This is a very rare opportunity to own a very rare and significant part of Sinn's history.
