Frequently asked questions

What is the exact lug width of the Omega De Ville 422.10.44.51.06.001?

The lug width of the De Ville 422.10.44.51.06.001 is 20mm. This is the width of the seat where the strap connects to the case between the lugs. This measurement is not adjustable and must match exactly the strap you wish to purchase.

What is the best strap material for the Omega De Ville 422.10.44.51.06.001?

Vegetable-tanned alligator remains the ideal choice to maintain the formal dress character of this model. It offers natural rigidity, refined characteristic grain, and a patina that ages beautifully. Vegetable-tanned calf leather represents a valid alternative for those desiring greater softness and daily versatility.

How do you change the strap on the Omega De Ville 422.10.44.51.06.001?

The strap is changed by removing the spring bars that secure it to the case. Using a spring bar removal tool (available at jewelers) or a small screwdriver, gently push the bar from one side to the other of the case. Ensure that the new strap has exactly 20mm lug width. If you are not experienced, consult a qualified watchmaker.

Can I use an aftermarket strap compatible with my De Ville 422.10.44.51.06.001?

Yes, provided the strap has a lug width of 20mm. Artisanal straps from Milano Straps are specifically designed for this width and crafted from superior quality materials. Always verify that the leather thickness is compatible with your case lugs.

How long does a leather strap last on a watch like the De Ville 422.10.44.51.06.001?

A quality leather strap with vegetable tanning lasts on average 3-5 years with daily use. Longevity depends on sun exposure, sweat, and humidity. A strap worn occasionally can last 7-10 years. Milano Straps offers an 18-month warranty on straps crafted at the Casati Milano atelier.
