Frequently asked questions
What is the lug width of the Omega De Ville 4642.72.31?
The lug width of the De Ville 4642.72.31 is 18mm. This width determines strap compatibility: measure internally between the two lug shoulders with a digital caliper to ensure perfect fit without lateral play.
Which strap pairs best with the platinum Omega De Ville 4642.72.31?
For a platinum watch, we recommend mahogany alligator with beige whipstitching or Italian calf leather with vegetable tanning in grey mole. Alligator offers elastic patina and natural pattern; vegetable-tanned calf develops noble grain over time. Both maintain aesthetic coherence with the platinum's coolness without competing visually.
How do you change the strap on the Omega De Ville 4642.72.31?
Strap change is performed by removing the lug pins (spring bars) with a dedicated tool (strap remover). Position yourself facing the watch, gently compress the internal spring of the bar, and slide outward. Reinsert the new strap by reversing the procedure. It is advisable to use Casati Milano for the first change or for custom straps.
Can I use a non-Omega aftermarket strap on my De Ville 4642.72.31?
Yes, provided it respects the 18mm lug width and is made with coherent materials (noble leather, accurate finishing). Milano Straps supplies artisanal straps in alligator, shell cordovan, and vegetable-tanned calf specifically compatible with this size. Construction quality and patina are essential to maintain the platinum's elegance.
How long does a leather strap last on a watch like the De Ville 4642.72.31?
An artisanal alligator or vegetable-tanned calf strap typically lasts 3-5 years with daily wear, extending to 5-7 years if alternated with other straps. Vegetable tanning develops noble patina that ages beautifully. Casati Milano guarantees 18 months on every custom strap, with maintenance and replacement of internal elastic fibers available.
