The De Ville 433.13.41.21.03.001 (aka: 43313412103001), seen from the bench

The Omega De Ville 433.13.41.21.03.001 is a 41mm stainless steel dress watch featuring the Co-Axial 8900 caliber, a certified chronometer movement with date function. The model has a 20mm lug width and represents the contemporary interpretation of the De Ville line, originally established in the 1960s. Its integrated bracelet design characterizes the modern De Ville aesthetic, though many owners choose to replace it with custom straps while maintaining the formal balance of the original design.

Frequently asked questions

What is the lug width of the Omega De Ville 433.13.41.21.03.001?

The lug width is 20mm. This measurement is standard for the contemporary 41mm De Ville and allows a balanced pairing between case and strap without excessive lateral volume.

Which strap is best for the Omega De Ville 433.13.41.21.03.001?

It depends on use and personal preference. For formal occasions, alligator with regular grain maintains the dress character of the model. For daily wear, aniline calf offers comfort and aging patina. Those seeking versatility can choose a black silk NATO or a satin rubber strap that allows quick look changes.

How do you change the strap on an Omega De Ville 433.13.41.21.03.001?

Removing the strap requires the use of a spring bar tool: insert the tip into the space between the lug and the bracelet, gently lever downward to release the spring bar, then extract the bracelet. Repeat for the other lug. To install the new strap, align the holes at the ends and reinsert the spring bar, ensuring it is fully locked on both sides.

Are aftermarket straps compatible with the De Ville 433.13.41.21.03.001?

Yes, provided they have a 20mm lug width. However, it is important that the strap is customized to the lug depth of your specific model: the De Ville requires greater precision than other Omega models to maintain the formal aesthetics of the design. A bespoke strap from an atelier guarantees the best aesthetic result.

How long does a leather strap last on an Omega De Ville 433.13.41.21.03.001?

Durability depends on material and use. An alligator strap with natural tanning lasts on average 3-5 years with ordinary care; aniline calf, being more absorbent, 2-4 years. With a rotation of at least two straps and periodic cleaning, durability extends significantly. A protective treatment every 6 months visibly prolongs the life of the strap.

The next step

The right strap isn't chosen. It is built, together.
