The De Ville 433.13.41.21.10.001 (aka: 43313412110001), seen from the bench

The Omega De Ville 433.13.41.21.10.001 represents six decades of watchmaking refinement. Born in the 1960s as an evolution of the Seamaster collection, this dress watch features a 41mm stainless steel case and an Omega 8900 Co-Axial Master Chronometer movement with hours, minutes, seconds, and date. The lug width is 20mm, reflecting the elegant case proportions and optimal balance between structural rigidity and aesthetic fluidity.

Frequently asked questions

What is the lug width of the Omega De Ville 433.13.41.21.10.001?

The lug width is 20mm. This dimension represents the internal distance between the two spring bar seats and is essential for selecting compatible straps. Verify with a digital caliper positioned perpendicularly to the seats to ensure millimetre precision.

What strap material is recommended for the De Ville 433.13.41.21.10.001?

To preserve the dress character of this model, we recommend alligator in dark shades (black, dark brown), vegetable-tanned calf leather for an aged patina, or shell cordovan in burgundy. A textile NATO is ideal for casual contexts. Avoid natural rubber, which contradicts the sophisticated aesthetic of the watch.

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

Position the watch on a soft cushion. With a spring bar tool, gently lift one spring bar by pushing inward, then extract the lug from the seat. Repeat on the other side. Insert the springs of the new strap into the seats while keeping the module in a stable position, ensuring the spring is fully seated. Check the movement before wearing.

Are aftermarket straps truly compatible with the De Ville 433.13.41.21.10.001?

Yes, but with care: the lug width is 20mm, which is a common standard. However, verify that the strap width at the base is adequate to the case geometry, to avoid excessive play or friction. Straps of artisanal quality from specialised manufacturers guarantee impeccable mechanical and aesthetic compatibility.

How long does a leather strap last on this Omega?

A quality leather strap (alligator, calf, shell cordovan) can last 3–5 years with ordinary maintenance and non-daily use on a dress watch like the De Ville. Durability depends on frequency of use, exposure to moisture and sunlight, and the specific material. Vegetable-tanned leather tends to patina and last longer; synthetic leather requires more frequent replacement.
