Zenith
Elite 16.3200.670/01.C831— lug 19mm

The lug width of the Zenith Elite 16.3200.670/01.C831 is 19 mm. This measurement represents the distance between the two spring bar pins that attach the strap to the case. To verify, use a digital calliper positioned perpendicular to the lugs, measuring the internal space from pin to pin. It is a non-standard dimension in the watchmaking landscape, which is why it requires bespoke-constructed straps designed specifically for this measure.

For this model, we recommend straps in alligator leather or vegetable-tanned calf leather. Alligator offers elegant natural texture that does not visually compete with the stainless steel case; available in dark brown, black or cognac. Vegetable-tanned calf develops authentic patina over time and imparts a handcrafted quality to the strap. NATO fabrics are compatible with special lugs and offer informal versatility. Avoid mass-market straps that do not respect the precision of the 19 mm lug width specification.

To change the strap, use a spring bar tool to eject the pins from the lugs. Position the tool in the space between the case and the strap, gently pushing inward to release the pin spring. Remove the old strap, verify that the pins are not corroded, then insert the new strap by aligning the holes with the pins. Press until you hear a click of secure fastening. If the pins appear corroded, replace them before installing the new strap to ensure durable retention.

Yes, at milanostraps.it you will find aftermarket straps constructed specifically for the 19 mm lug width. They are available in various leathers (alligator, calf, cordovan) and fabrics (NATO, canvas). Straps can be personalised in length, embroidered initials and stitching thread colour. The Casati Milano atelier also offers bespoke construction with personal leather selection and sartorial consultation via WhatsApp.

The lifespan of a leather strap depends on the tanning method and frequency of wear. A high-quality alligator or vegetable-tanned calf strap, worn regularly (5-6 days per week), maintains structural integrity for 4-6 years. Cordovan, being denser, can exceed 8 years. Ageing is natural: patina increases aesthetic appeal. The stitching remains reliable longer than the leather itself. Casati Milano guarantees 18 months on all constructed straps, including stitch repairs within this period.
