Frequently asked questions

What is the lug width of the Omega De Ville 424.13.40.20.01.002?

The lug width of this model is 20mm (internal distance between the strap attachment pins). This width is specific to the De Ville and ensures balanced proportions with the 39.50mm case. Always verify with a digital caliper, as manufacturing tolerances can vary between 19.8 and 20.2mm.

What is the best strap for the Omega De Ville 424.13.40.20.01.002?

Nile crocodile leather with vegetable tanning is the most coherent choice: its regular grain pairs perfectly with the brushed case finish, and the patina that develops over time creates a unique aesthetic story. Alternatively, shell cordovan offers natural semi-rigidity and exceptional longevity (15-20 years). For maximum formality, smooth black calf leather is unbeatable.

How do I change the strap on my De Ville 424.13.40.20.01.002?

You will need a spring bar removal tool. Position the watch on a soft surface. Insert the tool into the small groove under the lug, pushing inward to release the pin. Repeat on the other side. Be careful not to scratch the case. If uncertain, consult a professional—Casati Milano offers strap change service by appointment.

Can I mount an aftermarket strap on this Omega?

Absolutely yes, provided the lug width is 20mm. High-quality artisanal straps often deliver superior aesthetic results compared to original Omega straps. Always verify that the strap is compatible in width and that the pins pass freely through the case lugs.

How long does a leather strap last on this watch?

Durability depends on the material and usage. A vegetable-tanned crocodile strap, worn daily with proper care, lasts 5-8 years before requiring replacement. Shell cordovan can reach 15-20 years. Smooth calf leather, being more delicate, lasts on average 3-5 years. Regular maintenance (cleaning, drying after rain) significantly extends the strap's lifespan.
