Strap for Classic Date 42 Stainless Steel - Rose Gold / Silver / Bracelet

The lug width is 20mm. To verify, measure the distance between the two inner holes where the spring bar passes through the case lugs. It must measure exactly 20 millimetres. This dimension is critical: a strap with a different lug width will not mount correctly.

For the Oris Classic 01 733 7719 4371-07 8 20 12, we recommend quality leather—natural alligator, vegetable-tanned calf, or shell cordovan for those seeking evolved patina over time. A NATO strap in grey or khaki canvas offers daily versatility. Structured rubber remains ideal for nautical use or humid environments.

The Oris Classic 01 733 7719 4371-07 8 20 12 employs a straight pin pass-through system. Use a spring bar tool to gently push the pin from one side, freeing one end of the strap, then slide the pin itself out of the lugs. Insert the new 20mm strap by aligning the lug holes and reinsert the pin. Verify the pin is firmly seated on both sides.

Yes, any strap with a 20mm lug width is compatible. Ensure the construction quality matches your Oris investment: artisanal leather straps in full-grain vegetable tannage, cordura, or alligator guarantee longevity and lasting aesthetics, avoiding compromises on synthetic materials.

A well-made leather strap—vegetable-tanned calf, natural alligator, or shell cordovan—typically lasts 3–5 years with daily use and proper care (occasional cleaning, air drying, avoiding prolonged immersion). The patina that emerges during this period enriches aesthetic value. A NATO strap lasts longer since textile material is less susceptible to moisture wear.
