Strap for Oris Classic 01 733 7594 4331

The lug width of the 01 733 7594 4331 is 20mm. This measurement refers to the distance between the case attachment pins and determines which strap is compatible with your watch. To verify it, measure the distance between the lugs using a calliper or flexible ruler, ensuring you do not include the lugs themselves in the measurement.

We recommend an alligator Mississippi strap in military green or ebony black tones for the Oris Classic 01 733 7594 4331, as it emphasises the classical nature of the watch. Alternatively, a vegetable-tanned calf or a black NATO maintains aesthetic balance. Your choice depends on your personal style and how you intend to use the watch.

The strap on the Oris Classic is changed using a spring bar tool. Insert the flat tip of the tool into the lug hole, push gently downward to compress the internal spring, then extract the spring bar. Repeat the procedure on the opposite side and install the new strap by reversing the process. If you are inexperienced, we recommend seeking professional assistance.

Absolutely. Numerous artisanal straps of superior quality are designed for 20mm lug widths. Straps available through specialist retailers in Italian and foreign leather guarantee full compatibility with the Oris Classic whilst maintaining workmanship standards equal to or exceeding original straps, often at more competitive prices.

Longevity depends on the material and usage. A quality alligator strap lasts 5 to 7 years with regular daily wear. Vegetable-tanned calf lasts approximately 3 to 4 years with ordinary care. A canvas and cotton NATO easily exceeds 10 years. Durability extends considerably if you protect the strap from excessive water and occasionally apply a protective balm.
