The De Ville 434.15.34.20.55.001, seen from the bench

The Omega De Ville 434.15.34.20.55.001 is a 34 mm stainless steel watch representing the urban elegance evolution of a 1960s icon. It houses the Omega 8800 coaxial chronometer-certified movement and features a silver-grey dial with minimalist design. The 16 mm lug width is the sole compatible measurement for this model's strap attachment, essential for proper fitment and avoiding incorrect purchases.

Frequently asked questions

What is the lug width of the De Ville 434.15.34.20.55.001?

The lug width is 16 millimetres. This dimension represents the space between the pins that connect the strap to the case lugs. It is the only compatible size for this Omega model.

Which strap is ideal for the Omega De Ville 434.15.34.20.55.001?

Brown alligator is the most refined choice, followed by vegetable-tanned calf leather which develops a noble patina over time. For a casual alternative, grey canvas NATO straps maintain the watch's sobriety without formal aesthetic compromises.

How do you change the strap on a watch with 16mm lugs?

Use a spring bar tool to gently push the lateral fixing pins. Insert the tool tip into the pin hole, apply inward pressure and extract the pin. Repeat on the other side. Install the new strap by aligning the pins to the lug holes and pressing until you feel the locking click.

Are aftermarket straps compatible with the De Ville 434.15.34.20.55.001?

Yes, any strap with a 16mm lug width is compatible with this watch. It is essential to verify the declared width before purchase. Milano Straps offers a complete selection of straps customisable specifically for this size.

How long does a leather strap last on a watch worn daily?

A quality artisanal vegetable-tanned calf strap typically lasts 18–24 months with daily wear, developing natural patina. Alligator offers superior longevity (3–4 years) thanks to the natural structure of the scales being more resistant. Longevity depends on exposure to moisture, temperature and perspiration.
