You can usually find the reference number of your Oris strap engraved on the clasp. For metal bracelets, the reference number is located on the clasp, while for leather, rubber, and textile straps it is typically found on the inside of the strap. Please refer to the image below for guidance.
For Oris watches up to 20 years old, you can typically identify the correct strap reference by browsing our product archive on the official Oris website.
If your watch is older than 20 years, strap reference information may no longer be listed online. In such cases, we recommend exploring reputable watch communities, collector platforms, or vintage watch resources. You can also contact our customer service team with a photo of your watch and strap for further support.
