Zenith
Elite 03.2310.679/38.M2310— lug 20mm

The Zenith Elite 03.2310.679/38.M2310 features a lug width of exactly 20 millimeters. This measurement is critical: it must be verified with a digital caliper by measuring the distance between the inner edges of the two holes that accommodate the spring bars. An undersized strap will create vertical pin movement, while an oversized one won't fit at all. On milanostraps.it you'll find the entire collection of certified 20mm straps ready for installation.

The ideal strap depends on the intended use. For maximum formal elegance, we recommend dark mahogany or black Nile alligator, which amplifies the refinement of the ultra-thin caliber. For everyday versatility, European box calf in beaver or dove gray tones creates aesthetic harmony without compromise. Those seeking sportiness can opt for satiny cotton NATO. The Casati Milano atelier personalizes the choice based on your wrist and color preferences, with direct WhatsApp consultation.

The change requires extracting the two spring bars that connect the case to the original strap. Using a dedicated tool (pin remover), push the spring bars inward until completely disengaged. Next, align the new strap with the lug holes and reinsert the spring bars with uniform pressure until they snap into position. The procedure is straightforward but requires care: excessive lateral pressure can scratch the case. If you're not completely confident, the Casati Milano atelier offers the strap change service in a few minutes during an appointment visit.

Absolutely yes, provided the strap is precisely 20 millimeters. Artisanal straps from milanostraps.it are fully compatible: correct lug geometry is guaranteed, certified leathers are used, and constructive finishing is equivalent to Zenith standards. Many collectors prefer quality aftermarket options because they allow customization impossible with official options, plus they develop an individual patina over time.

Durability depends on the material and use. A premium quality alligator strap, with annual maintenance (gentle cleaning, conditioning), lasts 4-6 years of daily wear. European box calf, more vulnerable to moisture, resists 2-4 years under the same conditions. Artisanal straps from Casati Milano guarantee 18 months from delivery against manufacturing defects, with the possibility of professional reconditioning after the first year. Natural aging (development of creases, patina) is a desirable characteristic, not a defect.
