Frequently asked questions

What is the lug width of the Omega De Ville 5946.30.31?

The lug width of the Omega De Ville 5946.30.31 is exactly 18mm. This measurement should be verified with a digital caliper, measuring between the two metal lugs positioned at the sides of the case at 3 o'clock and 9 o'clock. An incompatible strap would not fit correctly.

What is the best strap for the Omega De Ville 5946.30.31 in platinum?

For the 5946.30.31 in platinum, black alligator leather with vegetable tanning represents the most appropriate choice, thanks to its fine grain texture that visually complements the elegance of the case. Dark brown shell cordovan offers an even superior luxury alternative for those seeking exceptional tactile density and a patina that develops over time.

How do I change the strap on my Omega De Ville 5946.30.31?

To change the strap, position the watch on a soft surface (felt pad). Using a spring bar tool, insert the lever under the internal spring of the lower lug and gently push outward to release it. Remove the old strap, insert the new one by aligning the holes with the springs, and press back until you hear a click. Verify that the strap is properly secured before wearing the watch.

Can I use a generic 18mm aftermarket strap on my 5946.30.31?

No, a generic 18mm strap may not be compatible due to manufacturing tolerances. The 5946.30.31 requires straps specifically designed for formal dress watch dimensions, with lugs cut to precision and high-quality stitching. Milano Straps offers certified straps compatible with your model.

How long does a leather strap last on the Omega De Ville 5946.30.31?

A high-quality alligator or shell cordovan strap, worn occasionally for formal occasions, can last 5-8 years. If worn daily, the lifespan reduces to 3-4 years. Vegetable tanning develops patina but requires maintenance: occasionally applying leather balm preserves flexibility and prevents cracking. The Milano Straps warranty covers 18 months of normal wear.
