Strap for Classic Date 42 Stainless Steel / Silver / Bracelet

The lug width of this model is 20mm. This dimension is measured internally, between the two axes of the lugs on which the strap attaches. Precise measurement is critical to ensure the strap is neither too tight nor too loose, which would compromise both aesthetics and functionality.

To maintain the design integrity of the Classic, we recommend alligator or vegetable-tanned calf leather in neutral tones (brown, black, burgundy). Both materials offer durability and develop a natural patina over time. For dynamic or humid environments, a heavy cotton NATO strap provides technical reliability whilst preserving the model's minimalist aesthetic.

Using a spring bar removal tool, insert the flat end beneath the lug and press gently downward to release the internal spring. Repeat on the opposite side. When installing the new strap, ensure the alignment holes are parallel to the lug, then insert the spring bar with even pressure until it clicks into place.

Yes, provided the strap is specifically dimensioned for a 20mm lug width. Always verify the manufacturer's technical specifications: compatible lug width ensures secure attachment. Caution: an incorrect lug width can cause oscillation or uneven pressure on the lugs, compromising both aesthetics and the watch's longevity.

A high-quality leather strap (alligator or calf) typically lasts 3–5 years with daily wear, depending on frequency of use, ambient humidity, and maintenance. Vegetable-tanned leather, thanks to natural tannins, allows periodic regeneration through conditioning with specific oils. Leather is not a consumable material: with proper care, your strap develops character and patina, evolving over time.
