Strap for Classic Date 37 Stainless Steel - Rose Gold / Silver

The lug width is 18 millimetres. This precise measurement is encoded in the reference itself and requires specifically 18mm straps to ensure perfect fit between the lugs without gaps or unsightly protrusions.

Vegetable-tanned calf leather in tan or black tones offers formal coherence, as its smooth texture contrasts elegantly with the case's satin finish. Alligator with cross-grain texture adds tactile sophistication. A premium cotton NATO provides sport versatility whilst maintaining proportions thanks to the case's modest diameter.

Locate the lug pins (small metal cylinders passing through the strap lugs). Use a spring bar tool to release the pin by pushing the internal spring. Once both ends are free, slide the strap away. To install the new strap, align the pins correctly—the spring must point inward—and insert them into the new strap's lugs, ensuring the pin seats fully.

Yes, any strap with an 18mm lug width is compatible. Spring bar pins are universal standard. We recommend artisanal leather or technical rubber straps that maintain aesthetic coherence with the case's classical proportions—avoid excessively thick straps or bulky buckles that would disrupt visual balance.

A quality vegetable-tanned calf strap lasts approximately 3–5 years with daily use, provided it dries quickly after moisture contact and avoids prolonged immersion. The patina ages naturally, increasing character. Structured rubber outlasts it—6–8 years—and is ideal for humid or athletic environments, requiring minimal maintenance.
