This is a Big Oyster, typically a 36mm case, compared to the usual 34mm OYSTER. Without a date display, it appears larger than its size suggests, giving it a powerful presence. The hand-wound, thin case provides a comfortable fit when worn. Ref. 6424 usually doesn't have holes on the dial case, but this watch comes with a matching Jubilee bracelet. The beautifully aged ivory dial, alpha hands, and blued steel hands are rare and enhance the antique feel. The watch was purchased from an authorized antique dealer in 2025 and is in good working order. The bracelet shows some stretching typical of antique pieces, but is fully functional. The warranty (see photo) cannot be provided as it includes the original owner's name. There are no other included accessories. Due to the nature of antique items, we cannot accept claims or returns. Please refrain from purchasing if you do not understand antique watches.
