Commitment to Authenticity

Our promise: Every new and used watch on Chrono24 is authentic. Our dealers are required to inspect each watch's authenticity and may only list original timepieces. However, should issues arise, you have 14 days upon delivery of your order to contact our support team and get your money back.

If the watch arrives and is defective or not as the seller described, you have 14 days to initiate a return and receive your money back.
