Frequently asked questions

What is the lug width of the De Ville 424.20.40.20.02.004?

The lug width of the Omega De Ville 424.20.40.20.02.004 is 20 millimeters. This width is the standard for this model and for many other classics in the De Ville collection. To measure correctly, remove the original strap and measure the distance between the lug shoulders where the strap is inserted.

What is the best strap for the Omega De Ville 424.20.40.20.02.004?

The best strap depends on your use. For formal occasions, authentic alligator with regular grain texture is unmatched. For versatile daily use, vegetable-tanned calf develops natural patina over time. Shell cordovan offers durability and noble aging. Milanostraps.it offers 20mm customizable straps in genuine leather, all compatible with your De Ville.

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

The De Ville 424.20.40.20.02.004 features push-out lugs: position the watch on a soft surface, use a spring bar tool to gently press the side lugs, slide the old strap downward. Repeat from the opposite side. To insert the new strap, insert the lug into the case guide and press until you hear the locking click. Casati Milano can assist if you prefer to entrust the operation to expert hands.

Can I use aftermarket straps with the Omega De Ville 424.20.40.20.02.004?

Absolutely yes. Any strap with a 20mm lug width is compatible with your De Ville. Milanostraps.it artisanal straps are built specifically for this standard and offer superior quality compared to factory straps. You can customize color, leather type, stitching, and initials.

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

A quality leather strap (alligator, calf, shell cordovan) lasts 2-5 years with daily use, depending on the tanning type and exposure to perspiration. Vegetable tanning is more resistant than chrome tanning. Casati Milano guarantees 18 months on custom straps. Wear is natural: the patina that develops is part of your watch's story.
