Strap for De Ville Prestige Co-Axial 36.8 Stainless Steel / Red Gold / Vintage Ivory

The lug width of the De Ville 424.23.37.20.09.001 is 19 mm. This measurement is precise and non-negotiable: an undersized strap will leave visible gaps between the lug and the passant, while an oversized one will not close correctly on the case. Always measure with a digital caliper on the lug shoulder, the part that enters the case passant.

For the bicolor red gold and steel De Ville, Nile alligator represents the most aesthetically coherent solution: its regular grain and natural grip convey authority, while the dark color amplifies the chromatic contrast. Quality alternatives include vegetable-tanned calf (which develops patina over time) and shell cordovan, ideal for those seeking a leather that evolves and tells a story of wear.

The De Ville 424.23.37.20.09.001 is equipped with screw-down lugs. To change the strap, use a specific tool (spring bar tool) to remove the spring bars that hold the strap to the lugs. Insert the tool into the slot beneath the lug, compress the spring bar, and remove the strap. Install the new strap by repeating the reverse operation. If you are not experienced, a local jeweler can perform this operation in 10 minutes.

Any strap with a 19 mm lug width is mechanically compatible. However, to maintain the aesthetic coherence of the De Ville, choose straps in noble leather (alligator, calf, cordovan) or high-quality FKM rubber. Avoid solid metal straps, as they would compete visually with the bicolor case. MilanoStraps offers a selection of artisanal 19 mm straps, customizable in size and color.

Durability depends on the material and usage. High-quality Nile alligator lasts 4-6 years if worn daily, while shell cordovan can reach 8-10 years thanks to fiber density. Vegetable-tanned calf has an average lifespan of 3-5 years. Factors such as humidity, sun exposure, and frequency of wear affect longevity. The Casati Milano atelier offers an 18-month warranty on custom straps, covering manufacturing defects and premature failures.
