Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Yellow Gold / Moonshine Sunburst / Bracelet

The Omega De Ville 424.20.40.20.08.002 has a lug width of 20mm. This measurement is the distance between the lugs protruding from the sides of the case and is essential for choosing a compatible strap. Always verify this dimension before purchase, as an 18mm or 22mm strap will not fit the case without modifications.

The best strap depends on your style and intended use. For maximum formality, we recommend dark brown alligator or vegetable-tanned calf: both enhance the Moonshine Gold case. If you prefer versatility, black calf remains the timeless option. For those seeking tactile authenticity and natural patina, red or burgundy shell cordovan creates sophisticated aesthetics. The buckle should be stainless steel with a deployant clasp for ease of adjustment.

To change the strap, you need to remove the spring bars that secure the strap to the case. Use a dedicated spring bar tool to gently lift the small lever holding the spring bar in place, then extract the bar. Repeat on the other side. Insert the spring bars of the new strap into the same holes, ensuring the retaining lever clicks properly into place. If unsure, consult a professional watchmaker to avoid scratching the case.

Yes, any strap with a 20mm lug width is compatible, regardless of brand. Artisanal straps from MilanoStraps, for example, are manufactured to the same attachment specifications (spring bars and deployant clasp) and offer superior build quality to many official Omega offerings. The key is to verify correct lug width measurement (20mm) and choose high-quality leather that won't damage the case.

Strap longevity depends on leather quality and usage. An artisanal alligator or vegetable-tanned calf strap typically lasts 5-7 years with daily wear, potentially longer if worn occasionally. Shell cordovan, being more resistant, can last 8-10 years. Patina and micro-abrasions are normal and add character. Expose the strap to moisture and perspiration moderately, store it in a dry location, and if necessary, have the leather treated with specific creams. Casati Milano straps include an 18-month warranty.
