Zenith
Pilot 04.2422.5011/78.C714— lug 20mm

The lug width of the Zenith Pilot 04.2422.5011/78.C714 is 20mm. This measurement refers to the distance between the spring bars that connect the case to the strap. It is essential to verify this dimension before purchasing an aftermarket strap, as an incorrect size would result in lateral play or difficulty in installation.

For the Zenith Pilot 04.2422.5011/78.C714, straps in Mississippi alligator or vegetable-tanned calf leather are recommended, both in brown or black tones. Alligator develops a patina that ages beautifully, while calf offers aesthetic restraint and durability. For more sporty uses, FKM rubber remains a functional choice.

Changing the strap requires the use of a specific spring bar tool. Insert the tip of the tool under the spring bar that connects the strap to the case, apply gentle pressure to compress the internal spring, and slide the bar outward. Repeat the operation on both sides. Install the new strap by following the reverse procedure, ensuring the spring bar is fully inserted.

Yes, provided the strap is made with a compatible 20mm lug width. Custom aftermarket straps, such as those crafted by the Casati Milano atelier, allow you to select exclusive leathers, customize dimensions and thickness, and add details such as gold initials or custom stitching, ensuring a completely bespoke experience.

The lifespan of a leather strap depends on leather quality, daily use, and maintenance. A high-quality alligator or calf strap can last 3-5 years of daily wear, developing a natural and elegant patina. Rubber has a similar lifespan but resists moisture better. Straps crafted by Casati Milano benefit from an 18-month warranty and can be restored through specialized maintenance services.
