Frequently asked questions
What is the exact lug width of the De Ville 4810.30.02?
The lug width is 20mm. This means the space between the case lugs, measured centre to centre, corresponds to 20 millimetres. It is essential to verify this dimension precisely before purchasing any aftermarket strap, as even a 0.5mm deviation compromises the fit.
Which strap do you recommend for the Omega De Ville 4810.30.02?
For the De Ville 4810.30.02 we recommend a black alligator or cognac brown alligator strap with a steel deployant. This combination maintains the understated elegance of the timepiece and develops an authentic patina over time. Alternatively, quality calf leather with a box finish offers daily versatility at a more accessible price point.
How do I change the strap on my De Ville 4810.30.02?
To change the strap you need to remove the spring bars from the case. Use a dedicated tool—a strap remover or specialised spring bar tool—to compress the internal spring and slide the bar out of the lug hole. Insert the new strap by aligning the holes with the spring bars and release the pressure. If you are not experienced with this operation, an expert (watchmaker or leather craftsman) will complete the job in 10 minutes.
Is an aftermarket 20mm strap compatible with the De Ville 4810.30.02?
Yes, any 20mm strap is compatible from a dimensional standpoint. However, technical compatibility does not mean aesthetic harmony. The De Ville requires a strap that respects its formal language: choose noble materials and understated finishes. Avoid sports straps, NATO straps in gaudy colours or reinforced canvas that conflict with the identity of the timepiece.
How long does a leather strap last on the Omega De Ville 4810.30.02?
A quality leather strap (alligator or calf) lasts on average 3-5 years with daily wear, equivalent to 4-5 days per week. Durability depends on exposure to moisture, heat and frequency of wear. A vegetable-tanned strap ages more quickly visually (develops patina), but remains functional. Casati Milano offers an 18-month warranty on all made-to-measure straps.
