Strap for De Ville Master Chronometer 34 Stainless Steel - Sedna Gold / Blue - Diamond

The lug width of this model is 16mm. This measurement is the fundamental parameter for selecting a compatible strap: the lugs are the two pins protruding from the case at the vertical extremities, and the distance between the center of one and the center of the other is exactly 16mm. Always verify this measurement by observing your watch directly before ordering a strap, as even minimal variations compromise proper fit.

Alligator remains the traditional choice par excellence: its porous structure with organized grain naturally complements the two-tone Sedna Gold-steel case. Vegetable-tanned calf is ideal if you seek a patina that evolves over time, parallel to that of Sedna Gold. Shell cordovan offers an almost vitreous surface and superior resistance. An FKM rubber strap is the sporty solution if the watch faces humid environments or dynamic activities.

The strap is replaced by removing the pins from the lugs (the 16mm lateral spaces). Use a spring bar tool—a specialized instrument with levers at the extremities—positioned under the spring pin, gently lifting until the pin slides toward the case center and releases. Repeat for the other side. Insert the new strap by first threading one end of the pin into one lug space, then lifting the strap to insert the other pin. Never force the pins: the movement must be fluid.

Yes, provided the strap has been manufactured for <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-16mm">16mm lugs</a>. Quality artisanal straps manufactured in Italy, such as those from Milano Straps, are crafted with precision for these dimensions. Always verify that the lateral slots (also called ears) have an internal space of 16mm to accommodate the Omega pins.

The lifespan of a leather strap depends on the material and use. Alligator and shell cordovan, if properly maintained, retain structural integrity for 3-4 years of daily wear. Vegetable-tanned calf offers similar durability, with the advantage that the patina it develops improves aesthetics over time. Continuous exposure to humidity, direct sunlight, and stress reduce leather lifespan. Milano Straps provides an 18-month warranty on bespoke straps created at Casati Milano.
