Strap for De Ville Hour Vision Master Chronometer Annual Calendar Sedna Gold / Blue / Bracelet

The lug width of the Omega De Ville 433.50.41.22.03.001 is 22mm. This is the distance separating the two metal lugs where the strap attaches to the case. Accurate measurement is essential: insert a digital calliper into the lower lug slot and read the internal distance between the metal edges. A measurement error would result in mechanical incompatibility with the case.

For the Sedna Gold case of 41mm, medium brown alligator represents the most elegant choice: the fine grain creates subtle visual contrast without competing with rose gold. Alternatively, vegetable-tanned calf offers natural patina that improves with time, whilst shell cordovan guarantees superior durability and intrinsic brilliance. For a sportier approach, technical polyamide NATO ensures robustness whilst maintaining minimal aesthetics.

Remove the watch from your wrist and place it on a flat surface. Locate the metal lugs on either side of the case and use a springbar tool (included with artisanal straps) to gently compress the internal spring of each support. Once tension is released, the old strap will slide away. Insert the new strap by sliding the lug support into the corresponding slot until you hear the click of securing. Verify that the strap is firmly attached before wearing.

Yes, provided the lug width is exactly 22mm. Artisanal straps produced by milanostraps.it are manufactured to technical specifications to ensure complete compatibility with Omega's original lugs. However, any strap with a lug width below or above 22mm will not fit correctly. We always recommend verifying dimensions before purchase.

Durability depends on material and usage. High-quality alligator, with proper maintenance (protection from standing water and occasional hydration), resists 4-6 years of daily use. Vegetable-tanned calf typically lasts 3-5 years, with patina improving over time. Shell cordovan, thanks to superior density, can exceed 6-7 years. FKM rubber offers the greatest longevity (8-10 years), but less aesthetic versatility. Casati Milano offers an 18-month warranty on all artisanal straps, with possibility of restoration.
