Strap for Classic Date 42 Stainless Steel / Blue / Bracelet

The lug width of this timepiece is precisely 20mm. This measurement represents the internal distance between the case lugs where the strap is fitted. It is essential to verify this dimension before ordering an aftermarket strap, using a digital calliper positioned between the lugs.

The choice depends on your intended usage. For formal contexts, we recommend calf leather with vegetable tanning or shell cordovan: both develop a natural patina over time. For daily sports use, a NATO fabric strap offers practicality and versatility. Rubber remains the technical choice for humid or aquatic environments. The 20mm lug width permits a broad selection without constructive limitations.

The strap is replaced by removing the lateral lugs. With the watch facing upward, use a spring bar tool (specific device for lugs) to compress the internal spring and extract it from the case hole. Once the lug is freed from one side, the strap slides away. Insert the new strap aligning it to the holes and reinsert the lug by compressing the spring until engagement. The operation requires care to avoid scratching the case.

Yes, any strap with a 20mm lug width is compatible. The artisanal straps from milanostraps.it are specifically produced for this measurement and guarantee precise fitting without lateral play. Always verify that the lateral lugs of the case have standard holes for spring bar insertion, a standard condition on all Oris Classic models.

Durability depends on the material and usage. Calf leather with vegetable tanning resists on average 18-24 months with moderate daily use. Shell cordovan, being denser, can last 24-36 months. Leather is a living material that ages naturally: perspiration, humidity and sun exposure accelerate wear. Artisanal straps made from superior quality leather develop an elegant patina during ageing, transforming the wearing process into an aesthetic advantage.
