Zenith
Pilot 16.1930.681/31.C725— lug 20mm

The Zenith Pilot 16.1930.681/31.C725 features a 20mm lug width. This width is determined by the distance between the two metal pins (spring bars) that protrude from the case lugs. To verify the measurement, use a digital caliper positioned between the two pins: the internal distance must correspond exactly to 20mm. It is essential to check this measurement before ordering a replacement strap to ensure correct and secure fit.

The ideal strap depends on your aesthetic preferences and intended use. For a classic and refined result, we recommend dark brown alligator (cognac) or black, which enhance the steel case and create an elegant contrast with the white dial. For those seeking daily comfort, vegetable calf or gummed calf in natural brown offers noble aging. If you prefer a sporty solution that references aeronautical origins, the dark blue NATO strap is the most authentic choice. FKM rubber is indicated for professional use and humid environments.

Changing the strap on the Zenith Pilot is a simple operation that requires a specific tool: a spring bar remover. Proceed as follows: 1) position the watch on a soft cloth to avoid scratches; 2) insert the tip of the remover into the small hole present on each lug, gently leveraging upward; 3) the metal pin (spring bar) will snap inward, allowing you to remove the old strap; 4) insert the new strap by aligning the holes with the pins; 5) press downward until it clicks. If you are unsure, rely on a professional: the Casati Milano atelier offers assistance and customization by appointment.

Any strap with a 20mm lug width is compatible with the Zenith Pilot 16.1930.681/31.C725. Online, on milanostraps.it, you will find a wide selection of straps in various leathers (alligator, crocodile, calf, vegetable calf) and technical materials (NATO, FKM rubber, silicone). Always ensure that the strap lug width corresponds to 20mm and that the strap is of certified quality. Customizable artisanal straps, such as those created by the Casati Milano atelier, offer the possibility to choose leather, color, thickness and type of stitching to perfectly adapt to your style and fit needs.

The durability of a leather strap depends on the material, quality of craftsmanship, and daily use. A high-quality alligator or crocodile strap lasts on average 3-5 years with regular use, developing over time a characteristic patina that gives an increasingly noble appearance. Vegetable calf has a similar lifespan but with a texture that changes more rapidly, especially if exposed to moisture and perspiration. A gummed calf strap, being more robust, can last 4-6 years. The Casati Milano atelier offers an 18-month warranty on all custom-made straps, guaranteeing construction quality and selected materials. Periodic maintenance (gentle cleaning, conditioning) significantly extends the life of the strap.
