Strap for De Ville Master Chronometer Stainless Steel - Yellow Gold / Champagne

The Omega De Ville 434.23.40.20.08.001 is fitted with 19mm lugs, a standard width for this generation of the De Ville collection. Lug width is the horizontal distance between the two attachment pins on the case. To verify, measure directly across the inner shoulders of the case with a ruler or examine the original strap at the attachment point.

Alligator in cognac or deep espresso tones enhances the gold/steel two-tone case, creating aesthetic cohesion between two luxury materials. Shell cordovan offers a lustrous patina that ages gracefully over time. For more understated options, vegetable-tanned calf leather in bordeaux or taupe grey ensures durability and versatility.

Remove the watch from your wrist. Using a spring bar tool, apply gentle pressure to one of the two lateral pins on the case to release the internal spring, then extract the pin itself. Repeat on the other side. Insert the new strap by aligning the holes with the pins, then reinsert the pins ensuring the spring clicks into position. Never force: a poorly inserted pin can irreversibly damage the case lugs.

Durability depends on the tanning method and usage. A quality alligator or shell cordovan strap, with basic maintenance (ensuring the watch does not remain wet), lasts 5-8 years under gentle daily wear. Vegetable-tanned calf typically lasts 3-5 years before requiring replacement. Artisanal quality, internal structural support and stitching construction reduce premature wear.
