Strap for De Ville Small Seconds Master Chronometer Stainless Steel / Silver / Bracelet

The lug width of the De Ville 434.10.41.20.02.001 is 19mm. This dimension is specific to this Omega model and does not fall within the most common industrial standards (18mm or 20mm). Verify the measurement by positioning a digital caliper perpendicular to the case lugs, from inside to inside. Only 19mm straps will fit correctly into the lugs.

Alligator remains the optimal choice for this watch: fine grain, natural patina that evolves over time, aesthetics coherent with the formality of the satin case. Vegetable-tanned calf represents a more casual yet authoritative alternative. Shell cordovan introduces reddish warmth, appropriate for those wishing to depart from formal purity. Avoid budget solutions or synthetic leather: this De Ville deserves constructive consistency.

The strap is replaced using a spring bar tool. Position the watch face-down, insert the thin pin into the lateral opening of the lug to compress the internal spring, then gently extract the metal pin. Repeat on the other side. Proceed carefully: hasty movement risks scratching the satin case. For a safe strap change, contact the Casati Milano team by appointment.

Yes, provided the width is precisely 19mm. Compatible straps from milanostraps.it are customizable and available in certified artisanal leathers. Verify that the strap has proportionate lugs (neither too wide nor too tight) and that the buckle is in satin steel for consistency with the case. Avoid generic straps from non-specialized suppliers.

A quality artisanal alligator or calf strap lasts an average of 3-5 years with conscious daily use, developing natural patina that increases overall aesthetics. Durability depends on tanning, frequency of use, and exposure to environmental factors (humidity, direct heat). Casati Milano guarantees artisanal straps for 18 months and offers periodic updates via WhatsApp to monitor wear and replacement needs.
