Strap for Classic Date Lady 28.5 Stainless Steel / Black / Bracelet

The lug width is 14mm. This measurement is critical when purchasing a compatible strap: measure from the inside of one lug to the inside of the other to verify accuracy. The 28.5mm case diameter is proportionately matched to this 14mm strap width, creating the visual harmony characteristic of vintage Swiss dress watches.

For the Oris Classic, we recommend straps in alligator leather (for formal contexts), quality calf skin (natural ageing), or cotton NATO fabric (daily versatility). Avoid strap thickness exceeding 1.5mm at the lug attachment, as this may stress the lug seats. Your choice depends on dial colour and intended use: a dress watch requires sober, harmonious materials.

Strap change is performed using spring bars (spring-loaded rods). Use a dedicated spring bar tool (nail tool or dedicated extractor) to release the lugs and remove the bars. Position the new strap, reinsert the lugs into the spring bars, ensuring they click securely. If uncertain, contact a qualified watchmaker or Atelier Casati Milano for professional assistance.

Yes, any strap with a 14mm lug width is compatible, provided it respects the maximum thickness of 1.5mm at the lug attachment. Milano Straps offers a dedicated collection of handcrafted 14mm straps in leather, alligator, shell cordovan and NATO, fully customisable and rapidly dispatched. Visit the website for suggested colour pairings.

A quality leather strap (vegetable-tanned or chrome-tanned) lasts 3-5 years with moderate daily use, developing patina and character over time. Longevity depends on exposure to moisture, light and perspiration. Rubber straps remain unchanged but may crack after 4-6 years. Milano Straps offers replacement and routine maintenance services to extend your strap's serviceable life.
