Thank you very much for viewing. This is a Blancpain vintage Fifty Fathoms Aqualung automatic wristwatch. I cannot distinguish between original and aftermarket parts, nor can I tell if it has been redone. Please make your judgment based on the photos. The history of past overhauls is unknown, so parts other than genuine parts may have been used. Please consider this item only if you understand the characteristics of vintage and antique items. Brand: BLANCPAIN Model: FIFTY FATHOMS AQUA LUNG Case Material: SS Condition: Running Movement: Swiss made (Blancpain engraved) Size: 41mm Thickness: 14mm Other: Rotating bezel working, aftermarket strap Accessories: None Please understand that I am aware that it is not 100% original, and I have purchased and collected it as such. I will accept returns if there are any misrepresentations or defects on my part. In that case, please contact me within 2 days of receiving the item. I am sorry, but I cannot accommodate requests after more than 2 days. I will also answer inquiries to the best of my ability, so please feel free to contact me.
