Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Vintage Grey / Bracelet

The Omega De Ville 424.10.40.20.06.001 has a lug width of 20 mm. This is the standard lug width for the De Ville since the original version from the 1960s, a direct consequence of the 39.50 mm case diameter. To verify strap compatibility, always measure the width between the two inner edges where the strap contacts the case lugs: tolerance is virtually zero, 20 mm is the exact specification.

Alligator remains the most sophisticated solution: the geometric texture of its scales creates aesthetic dialogue with the case's satin finish. Shell cordovan from horse leather represents the alternative for those who prefer the warmth of natural patina and aging over time. Vegetable-tanned calf offers softness and declarative aging. We advise against NATO fabric: the De Ville requires an aesthetic foundation consistent with its formal aura.

Strap replacement is performed via spring bars positioned at the lug extremities. Use a specific tool to depress the internal spring and gently extract the old strap. Ensure the spring bars remain intact during the operation. If you are not experienced, it is preferable to consult a watchmaker or Casati Milano's service to avoid compromising the delicate case attachments.

Any strap with a 20 mm lug width is compatible with the De Ville 424.10.40.20.06.001. MilanoStraps offers a dedicated selection of 20 mm straps in premium materials (alligator, shell cordovan, calf, vegetable tanning, rubber). All available straps are tested for geometric and constructive compatibility with this lug width.

The lifespan of a leather strap depends on usage intensity, climatic conditions, and maintenance. A high-quality alligator or shell cordovan strap can remain in excellent condition for 8-12 years of daily wear. Vegetable-tanned leather tends to develop patina and wear more rapidly (4-6 years), but this is part of its aesthetic appeal. Casati Milano guarantees 18 months on materials, regardless of natural wear, and offers maintenance services and replacement of worn components.
