Frequently asked questions
What lug width does the Omega De Ville 5945.30.31 have?
The Omega De Ville 5945.30.31 requires a lug width of 20 mm. This attachment width is proportionate to the 38.70 mm case diameter and is characteristic of Omega dress watches from the 1960s. Always measure from the inside of one lug to the inside of the other to verify compatibility with precision.
Which strap pairs best with the De Ville 5945.30.31 in platinum?
Black or dark brown alligator is the most balanced choice: the leather does not compete with platinum but enhances it. Secondarily, vegetable-tanned calf in bourbon or mahogany tones creates warm contrast without aesthetic conflict. For informal contexts, a silk or linen NATO maintains versatility without compromise.
How do I change the strap on my Omega De Ville 5945.30.31?
First remove the <a href="/pages/termine-glossario/deployante">deployante</a> (buckle with side buttons) from the old strap: press the levers to release it. Next, free the spring bars from the case lugs using a dedicated tool or a blunt knife. Insert the new 20 mm strap into the attachments and close the spring bars. Finally, attach the <a href="/pages/termine-glossario/deployante">deployante</a> to the new strap. If uncertain, entrust it to Casati Milano atelier.
Can I use an aftermarket strap on an Omega De Ville 5945.30.31?
Yes, provided the lug width is precisely 20 mm. Always verify with a ruler: even 1 mm difference compromises the fit. Milano Straps offers <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">certified quality 20 mm straps</a> compatible with your De Ville, with customization options in leather and color.
How long does a leather strap last before it needs to be replaced?
An alligator or vegetable-tanned calf strap, if treated with care, lasts 3–5 years with daily wear. Lifespan depends on exposure to moisture, direct sunlight, and frequency of use. Straps crafted by Casati Milano include an 18-month warranty and can be restored through re-surfacing. Periodic maintenance with appropriate conditioner significantly extends the useful life of the leather.
