The De Ville 424.20.33.20.52.001 (aka: 42420332052001), seen from the bench

The Omega De Ville 424.20.33.20.52.001 is a 32.7 mm two-tone stainless steel and 18k yellow gold timepiece, powered by the Co-Axial caliber 2500 with certified chronometer precision. The watch features a silver silk dial with hour, minute, second and date display, housed in a 10.4 mm case with screw-back caseback. Its 16 mm lug width requires carefully selected straps for proper proportion and comfort.

Frequently asked questions

What is the exact lug width of the Omega De Ville 424.20.33.20.52.001?

The lug width is 16 millimetres. You can verify it by measuring with a calliper the distance between the centres of the two horizontal pins that hold the strap. This dimension requires specific straps, which are less common compared to standard 18 or 20 millimetre sizes.

What strap material is recommended for the De Ville 424.20.33.20.52.001?

Genuine alligator is the most coherent choice for this bicolour dress case: the marked grain and the patina that develops over the years reflect the timeless elegance of the De Ville. Vegetable-tanned calfskin and shell cordovan are excellent alternatives for those seeking less formality while maintaining perceivable quality.

How do you change the strap on this Omega?

The strap is secured with two pins (bayonet lugs or spring bars, depending on the model). To change them, use a dedicated tool (spring bar tool) to compress or extract the pins. Position the watch on a soft cloth, work gently to avoid scratching the case, and proceed with patience. If you have any doubts, contact a professional watchmaker or the Casati Milano atelier for assistance.

Is the strap I purchase from Milano Straps compatible with my De Ville?

Yes, if you choose straps specifically 16mm from the dedicated collection. Always verify that the strap is sold with pins suitable for your watch (some straps require additional pins). Milano Straps customises length and technical specifications: contact the Casati Milano atelier for personalised advice.

How long does a leather strap last on a watch like the De Ville?

A quality leather strap (alligator, calfskin, shell cordovan) lasts an average of 3–5 years with moderate daily use. It depends on environmental humidity, frequency of wear and maintenance: avoid prolonged water exposure, apply a light leather conditioner occasionally, store in a dry environment. Milano Straps guarantees 18 months on its bespoke straps and can assess repairs and regenerations.
