Frequently asked questions
What is the lug width of the Omega De Ville 424.55.33.20.55.007?
The lug width of this model is exactly 18 mm. This measurement is proportionate to the case diameter of 32.70 mm and ensures correct strap aesthetics. To verify compatibility, measure the distance between the two lugs protruding from the case: it should be precisely 18 mm.
What strap do you recommend for the Omega De Ville 424.55.33.20.55.007 in Red Gold?
For this red gold case we first recommend alligator in medium brown or cognac tones: the natural grain and softness harmonize perfectly with the warmth of gold. An elegant alternative is vegetable-tanned calf leather in dark brown or black, which develops natural patina with use. Shell cordovan remains the choice for those seeking compact texture and intrinsic luster.
How do I change the strap on the Omega De Ville 424.55.33.20.55.007?
Strap change is performed by unscrewing the spring bars that connect the strap to the case, using a dedicated tool (spring bar tool). Remove the bars, slide them out of the old strap, insert them into the new one while keeping the internal spring in the correct position, then reinsert them into the case lugs and tighten gently. If you lack experience, consult a trusted watchmaker.
Which aftermarket straps are compatible with the Omega De Ville 424.55.33.20.55.007?
Any strap with an 18 mm lug width is compatible. You can choose from online collections (such as our 18 mm options available on milanostraps.it), or commission a made-to-measure strap from Casati Milano atelier with personal selection of leathers and customized construction details.
How long does a leather strap last on an Omega De Ville?
A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3-5 years with daily use. Durability depends on humidity, cleaning frequency, and maintenance. Straps made in atelier with vegetable tanning age beautifully and can be restored. Milanostraps straps carry an 18-month warranty; Casati Milano straps come with 18 months warranty and the possibility of lengthening or partial replacement.
