The lug width is 19mm. This measurement represents the distance between the inner edges of the lugs where the strap attaches. Always verify by measuring perpendicular to the case between the lugs with a ruler, without compressing the case.

For daily elegant wear, a dark brown alligator or vegetable-tanned leather are ideal. For diving, FKM rubber guarantees resistance to salt water. NATO straps offer the best compromise between functionality and versatility.

Use a spring bar removal tool to insert the tip under the spring bar (the small spring securing the strap). Lift gently to free the strap from the lugs. Insert the new strap by pushing the spring bar into the holes until it clicks. No permanent tools required.

Yes, provided the lug width is 19mm and the strap thickness is between 3mm and 4mm. Milano Straps offers artisanal straps specifically tested on Oris models, with a guarantee of perfect fit.

A quality leather strap on a diving watch has an average lifespan of 3-5 years if not subjected to frequent submersion. Salt water and chlorine accelerate ageing. FKM rubber maintains elasticity for 8-10 years. We do not recommend natural leather for regular diving; use rubber and alternate leather for daily wear.
