D-Series D05-0804— lug 20mm

The D05-0804 features a 20.00 mm lug width, measured perpendicularly from the internal tip of one lug to the other. This specification is inherent to the model and ensures proper visual proportions between case and strap.

Selection depends on intended use and personal taste. For formal elegance, we recommend vegetable-tanned leather in dark brown or black alligator. For sports versatility, a thick-weave NATO in anthracite grey. For minimalist purity, black FKM rubber with satin-finished steel deployante.

Position the watch on a soft surface. Using a spring bar tool, insert it into the lateral hole of the lug from the internal side and lift the spring bar. Remove the old strap. Install the new strap, ensuring both lugs align properly and the spring bar clicks securely into place.

Yes, provided the strap is specifically designed for 20 mm lug width. Verify that the internal clearances of the spring bar match your lug dimensions. Bespoke artisanal straps guarantee maximum compatibility and superior construction quality versus generic options.

Durability depends on tanning quality and usage intensity. A vegetable-tanned leather of superior grade, with ordinary maintenance (occasional cleaning, annual conditioning), retains full functionality for 3-5 years. Natural wear accelerates after the third year of daily wear.
