We do not accept questions after purchase. We do not accept returns under any circumstances, so please purchase with your understanding. This is a valuable model, but it is being sold at a low price due to its condition. Grand Prix Orient Special Hand-wound 1960s Winding the mainspring and setting the hands are not a problem. The accuracy is also reasonably good. *The reason for the condition is that there is a problem with the back cover. There is damage to the opening, and because there was a concern that it might come off, it was lightly glued (photo 6 is easy to understand). There are other overall scratches on the case and the windshield. We are looking forward to purchases from those who understand antique watches. #GrandPrixOrient #OrientGrandPrix #OrientOlympia #OrientAntique #OrientVintage #SeikoAntique #SeikoVintage #CitizenAntique #CitizenVintage #OrientStar #RoyalOrient
