Zenith
Pilot 11.1941.679/94.C814— lug 20mm

The lug width of the Zenith Pilot 11.1941.679/94.C814 is 20mm, a standard measurement inherited from civil aviation chronograph specifications of the 1940s. To verify correct measurement, position the watch with the dial facing downward and measure with a digital caliper the linear distance between the geometric centers of the two lateral attachment pins on the case. On Milano Straps you will find a wide selection of 20mm straps compatible with this model.

The best strap depends on intended use. For formal and daily wear we recommend Mississippi alligator or vegetable-tanned calf leather, which develop a natural patina over time creating a sophisticated aesthetic effect. For intensive use or challenging environments, polyamide NATO offers abrasion resistance and simplified maintenance. FKM rubber is the correct choice if the watch may come into contact with aeronautical lubricants.

The procedure requires a spring bar tool, a fork-shaped instrument that allows you to compress laterally the spring bars that secure the strap to the case. Insert the tool in the gap between the lug and the case on both sides, lift the lateral metal pins, and slide the old strap outward. Insert the new strap by positioning one end first, then compress the spring bar and snap the other end into position. If you are unsure, contact Casati Milano for professional strap replacement.

Yes, the Zenith Pilot Type 20 Extra Special accepts all 20mm lug width straps thanks to its standard spring bar attachment system. Milano Straps offers a curated collection of 20mm leather and textile straps compatible with this reference. We recommend verifying that the strap has a minimum width of 18mm to ensure mechanical stability in the case slot.

Durability depends on frequency of use and environmental conditions. A high-quality vegetable-tanned calf strap, worn daily, maintains structural integrity for 3-4 years before requiring replacement. Alligator, thanks to its more resistant fiber, can last 4-6 years. Wear accelerates in humid environments or with direct exposure to perspiration. Casati Milano offers an 18-month warranty on all bespoke straps, covering manufacturing defects and permitting replacements in case of premature deterioration due to manufacturing defects.
