Strap for De Ville Power Reserve Master Chronometer Stainless Steel - Yellow Gold / Silver

The lug width of the Omega De Ville ref. 434.23.41.21.02.001 is 19.00mm. This standard measurement allows for direct fitting of straps crafted to this specific width, without the need for adapters. Measurement is performed using a digital caliper from the center of the upper lug to the center of the lower lug.

For the De Ville 434.23.41.21.02.001 we recommend alligator in vegetable tanning for maximum formal elegance, or Annonay calf for more dynamic applications. Shell cordovan represents an intermediate choice with accelerated patina development. For sports contexts, FKM rubber or technical NATO straps maintain formal integrity while emphasizing resistance to 100 meters water resistance.

The strap is replaced by removing the two spring bars that connect the strap to the case lugs. Use a dedicated tool (spring bar tool) to gently compress the small hook that holds the spring bar in place, then extract the spring bar and slide off the old strap. Insert the new strap by aligning the holes with the lugs and reset the spring bars until the clicking confirmation.

Yes, any strap with 19mm lug width is compatible with the De Ville 434.23.41.21.02.001. Milano Straps offers artisanal straps in various materials (alligator, calf, shell cordovan) customizable in size, initials and stitching type, ensuring perfect compatibility without case modifications.

The lifespan of a leather strap depends on usage, tanning type and leather quality. Alligator and shell cordovan in vegetable tanning guarantee 3-5 years of daily use before replacement is needed, developing a noble patina over time. French calf resists slightly less but maintains excellent aesthetics for 2-4 years. Synthetic tanned leather straps have shorter lifespan but better water resistance.
