The De Ville 424.27.33.20.55.001 (aka: 42427332055001), seen from the bench

The Omega De Ville 424.27.33.20.55.001 represents a contemporary evolution of the dress watch standard established over sixty years. This model combines rose gold Everose and stainless steel 316L, featuring a mother-of-pearl dial and a 32.7 mm case diameter. Powered by the Omega Caliber 2500 CO-Axial movement, certified Chronometer with precision within 4 seconds per day, it offers essential timekeeping functions including hours, minutes, seconds, and date window. The 16 mm lug width is deliberately calibrated for refined proportions.

Frequently asked questions

What is the lug width of the Omega De Ville 424.27.33.20.55.001?

The lug width of this model is 16 millimetres. This is a precise and non-standard measurement; ensure that the strap you choose is explicitly compatible with this dimension, as universal straps may not fit correctly.

Which strap is best suited to the Omega De Ville 424.27.33.20.55.001?

For this dress watch, we recommend an alligator strap (black, dark brown, or cognac) for formal occasions, or vegetable-tanned calf leather if you desire a natural patina that evolves over time. For casual wear, a rubber or NATO strap ensures practicality and durability.

How do you change the strap on the De Ville 424.27.33.20.55.001?

Use a spring bar tool to remove the spring bars that secure the strap to the case lugs. Position the tool in the spring bar groove, gently push inward and lift the strap. Repeat on the other side. Install the new strap by reversing the process, ensuring that the spring bars are fully inserted into the attachments.

Is there an aftermarket strap compatible with reference 424.27.33.20.55.001?

Yes, straps produced for the 16mm lug width are compatible with this model. Verify that the seller explicitly indicates compatibility with this width; specialist brands such as Milano Straps offer certified and customisable solutions.

How long does a leather strap last on this watch?

A quality leather strap (alligator or vegetable tanned calf) lasts on average 3–5 years with daily use, provided regular maintenance: avoid prolonged moisture, protect from direct sunlight and treat periodically with leather balms. Natural rubber offers greater longevity (5–7 years). Milano Straps provides an 18-month warranty on all bespoke straps.
