Strap for Classic Date Lady 28.5 Stainless Steel / Blue

The lug width of the Oris Classic 01 561 7718 4075-07 5 14 35 is precisely 14 millimetres. This dimension is measured by calculating the distance between the centre of the left lug hole and the centre of the right lug hole on the case. It is essential to verify this measurement before purchasing an aftermarket strap, as a 14mm lug width is not compatible with alternative sizes.

For the Oris Classic 28.5mm, materials that respect the understated aesthetic of the model are recommended. A vegetable-tanned leather strap with visible grain enhances the formal sobriety of the stainless steel case. Vegetable-tanned alligator, featuring natural scaled texture, represents a structured alternative. For informal daily use, a NATO strap in technical canvas offers versatility, whilst burgundy shell cordovan combines elegance with evolving patina over time. Vulcanised rubber is ideal for those frequently exposing their wrist to moisture.

The Oris Classic strap is changed using a spring bar tool (lever extractor). Position the tool in one of the lateral lug holes on the case, lift slightly to retract the internal spring, and slide the strap out from the lugs. Repeat the operation from the opposite side. Installation of the new strap requires threading the lugs through the lug holes and verifying that the spring bars seat fully in their designated positions. If the strap is fitted with a deployante buckle, ensure the folding mechanism is positioned on the underside of the wrist.

All straps constructed for 14mm lug width are compatible with the Oris Classic 01 561 7718 4075-07 5 14 35. Milano Straps offers a dedicated collection of 14mm straps, available in artisanal leather (vegetable-tanned, alligator, shell cordovan), NATO, elastic and vulcanised rubber. Compatibility is guaranteed by the standardisation of lug width: no mechanical adjustment is necessary.

The lifespan of a natural leather strap depends on usage intensity and the constructive quality of the material. A vegetable-tanned leather strap, properly maintained and not exposed to prolonged moisture, can guarantee 3-5 years of daily use before requiring replacement. Shell cordovan straps, owing to the superior density of the collagen fibre, can last 5-7 years. Factors such as perspiration, direct sun exposure and repeated torsion accelerate wear. Preventative maintenance (regular cleaning, treatment with specific protective creams) significantly extends the useful life of the strap.
