The De Ville 434.20.34.20.02.003 (aka: 43420342002003), seen from the bench

The Omega De Ville 434.20.34.20.02.003 is a 34mm dress watch combining Sedna Gold and stainless steel, embodying Swiss watchmaking heritage with a classical 1960s design aesthetic. It features the Omega 8800 automatic movement with Co-Axial escapement, date window at 3 o'clock, COSC chronometer certification, and 4 Hz oscillation frequency. The watch requires a precisely measured 16mm lug width for proper strap compatibility and proportional design integrity.

Frequently asked questions

What is the exact lug width of the Omega De Ville 434.20.34.20.02.003?

The lug width of the Omega De Ville 434.20.34.20.02.003 is 16mm. This measurement corresponds to the distance between the two spring bars that protrude from the case lugs. It is essential to verify this measurement before purchasing an aftermarket strap, as 18mm or 20mm straps would be oversized and compromise the proportions of the case.

Which type of strap pairs best with the Omega De Ville 434.20.34.20.02.003?

For this two-tone 34mm case with Sedna Gold and steel, a dark brown alligator or vegetable-tanned calf leather represent the most elegant choices. Alligator amplifies the precious gold element, while calf leather develops a natural patina over time. For daily wear, structured rubber in sober colors or canvas NATO offer versatility without aesthetic compromise. Avoid excessive textures or uncontrolled materials such as suede.

How do I change the strap on the Omega De Ville 434.20.34.20.02.003?

Strap change is accomplished via the two spring bars located at the case lugs. Use a spring bar tool or a small flat screwdriver to gently compress the pins and slide them out of the bars. Keep the case stable during the operation. Once the old strap is removed, insert the new spring bars into the lugs and secure them firmly. If you are unfamiliar with the procedure, it is advisable to consult a professional watchmaker.

Are there aftermarket straps compatible with the 434.20.34.20.02.003?

Yes, any commercial strap with a 16mm lug width is compatible with the Omega De Ville 434.20.34.20.02.003. Ready-to-ship solutions are available online, customizable in material, color, closure size, and thread color. For a bespoke experience, the Casati Milano atelier creates custom straps in selected leather, with an 18-month warranty and WhatsApp support during production.

How long does a leather strap last on the Omega De Ville 434.20.34.20.02.003?

The lifespan of a leather strap depends on usage intensity, tanning type, and care. A quality alligator with vegetable tanning can last 5-7 years with moderate use, developing a patina that increases aesthetic value. Classic calf leather with vegetable tanning has similar durability. Structured rubber is more resistant and can exceed 10 years. To extend longevity, avoid prolonged exposure to water and humidity, and periodically apply a natural conditioner. Casati Milano straps include an 18-month warranty and maintenance support.
