Frequently asked questions

What is the lug width of the De Ville 433.10.41.21.02.001?

The Omega De Ville 433.10.41.21.02.001 has a <a href="https://milanostraps.it/pages/termine-glossario/misura-ansa">lug width</a> of 20mm, the classic standard for sports watches and dress watches of medium to large sizes.

Which leather strap is best suited for the De Ville?

For the De Ville 433.10.41.21.02.001 we recommend polished <a href="https://milanostraps.it/pages/termine-glossario/alligatore">alligator</a> or <a href="https://milanostraps.it/pages/termine-glossario/shell-cordovan">shell cordovan</a> in dark shades (black, burgundy) that enhance the polished stainless steel case. The leather grain should remain fine to avoid competing visually with the understated dial.

How do you change the strap on this Omega?

Strap replacement requires the use of a spring bar tool to extract the springs from the <a href="https://milanostraps.it/pages/termine-glossario/misura-ansa">20mm lug width</a>. Position the tool in the lug hole, gently push the spring toward the center of the case and slide the strap out of the housing. For Milano Straps with <a href="https://milanostraps.it/pages/termine-glossario/deployante">deployant clasp</a>, the procedure is even simpler.

Are there certified aftermarket straps for the 433.10.41.21.02.001?

Each strap is tested with original springs and can be customized in <a href="https://milanostraps.it/pages/termine-glossario/concia-vegetale">vegetable tanning</a> for superior durability.
