Frequently asked questions

What is the lug width of the Omega De Ville 434.23.28.60.55.001?

The lug width of the Omega De Ville Trésor 434.23.28.60.55.001 is 13mm. This measurement refers to the distance between the case lugs: it is essential to ensure that the strap is compatible with this exact width to avoid play or misalignment. A 12mm or 14mm strap will not fit properly.

What is the best strap for the Omega De Ville 434.23.28.60.55.001?

For this watch we recommend alligator in cognac or tobacco tones, which enhances the mother-of-pearl dial while maintaining sobriety. Alternatively, vegetable-tanned calf offers elegant texture and ages beautifully. Shell cordovan is ideal for those seeking rigidity and natural lustre.

How do you change the strap on this Omega De Ville?

The strap is changed using a dedicated tool to remove the spring bars. You need to gently press the internal spring mechanism of the pin, extract it from the seat in the case, and then insert the new strap by aligning the holes before snapping the pins into place. We recommend having this operation performed by a professional to avoid damage to the case.

Can I use an aftermarket strap on this Omega model?

Yes, provided the lug width is exactly 13mm. Avoid standard straps in 14mm, 12mm or other sizes. A quality artisanal strap (alligator, cordovan, vegetable-tanned calf) is not only compatible, but further enhances the elegance of the De Ville Trésor with superior materials compared to factory equipment.

How long does an artisanal leather strap last on this watch?

An artisanal strap in fine leather (alligator, shell cordovan, vegetable-tanned calf) lasts an average of 5-8 years if worn daily, with variability depending on climate, wear and frequency of use. Humidity accelerates aging, while dry climates slow down the process. Casati Milano offers an 18-month warranty on all its artisanal straps.
