The De Ville 424.20.40.20.02.005 (aka: 42420402002005), seen from the bench

The Omega De Ville 424.20.40.20.02.005 represents the contemporary evolution of a family founded in 1962, featuring a bicolour case combining 18K yellow gold and stainless steel, 39.50mm in diameter, equipped with the Omega 2500 Co-Axial chronometer-certified movement. The 20mm lug width is a deliberate construction choice that redefines the space between wrist and case. The patented Co-Axial escapement system reduces component wear by eliminating lateral friction, with a frequency of 25,200 oscillations per hour, a power reserve of 42 hours, and precision of ±5 seconds per day under normal conditions.

Frequently asked questions

What is the lug width of the Omega De Ville 424.20.40.20.02.005?

The lug width of the Omega De Ville 424.20.40.20.02.005 is 20mm. This measurement represents the distance between the two case lugs where the strap is inserted. It is essential to order straps compatible with this specific lug width to avoid visible gaps between the lugs and the strap itself.

Which strap material is best suited for the De Ville 424.20.40.20.02.005?

For this two-tone case in yellow gold and steel, natural alligator in grey or tobacco brown tones represents the supreme choice for formal elegance. Alternatively, vegetable-tanned calf leather in dark brown is more versatile for everyday wear, while black FKM rubber keeps the design prominent without chromatic distractions.

How do you measure the lug width of the Omega De Ville to order the correct strap?

To verify the lug width of your De Ville, observe where the strap connects to the case through the removable pins. Measure the horizontal distance between the two lugs: it must be 20mm. You can also consult the watch reference (424.20.40.20.02.005): the second numeric block '20' encodes precisely this measurement.

Is the De Ville 424.20.40.20.02.005 compatible with aftermarket straps?

Yes, the De Ville is fully compatible with artisanal quality aftermarket straps. It is however essential to order straps specifically for 20mm lug width, not to be confused with 22mm versions of the same family. Online you will find artisanal straps ready for shipment and customizable in sizes, finishes and colours.

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

A quality leather strap (alligator, calf, shell cordovan) worn daily on an Omega De Ville has an average lifespan of 3-5 years before requiring replacement. Durability depends on frequency of use, maintenance care (moisture protection, periodic cleaning) and leather type. Vegetable tanning develops a natural patina that enhances aesthetics over time.
