Zenith
Pilot 03.2241.405/51.C915— lug 22mm

The Zenith Pilot Type 20 Extra Special, reference 03.2241.405/51.C915, features a lug width of 22mm. This measurement represents the distance between the upper and lower attachment points on the case, and is the decisive parameter for selecting a compatible strap. A 22mm lug width is standard for aviation chronographs of medium-large caliber, such as this 43mm model.

The choice depends on intended use and aesthetic preferences. For historical authenticity and versatility, a NATO in midnight blue or anthracite grey harmonizes perfectly with the lacquered dial and military heritage. For those seeking tactile elegance and temporal patina development, an alligator with vegetable tanning in dark brown offers a companion that evolves over time. If practicality without compromise is your priority, a fine-grained calf leather with textured finishes ensures durability and easy maintenance. All these materials are available in the 22mm width compatible with this Zenith.

The strap is secured to the case via spring bars positioned at the two ends of the lug. To remove the strap, use a dedicated spring bar tool to compress the bar and extract it from the case lug. Once the lug is free, insert the new strap by threading the spring bar through the lower loop, then the upper loop, ensuring the bar clicks securely into place. The Zenith requires no soldering, allowing quick and reversible changes even while traveling.

Yes, the Zenith Pilot 03.2241.405/51.C915 accepts aftermarket straps of 22mm width crafted by specialised artisanal manufacturers. On milanostraps.it you will find a selection of 22mm straps customisable in leather (alligator, calf, shell cordovan), technical fabric (NATO, canvas) and rubber, ready for shipment or bespoke creation at Casati Milano atelier with direct leather selection and bespoke stitching details.

Durability depends on material and usage patterns. A standard calf strap, subject to daily wear and moderate humidity, maintains functional integrity for 3–5 years; an alligator with vegetable tanning, being denser and more resistant, easily exceeds 7–8 years with occasional care. A technical NATO polyester strap can endure 10+ years without functional degradation. To extend the life of any leather strap, avoid prolonged saltwater exposure, clean stains with a damp cloth, and apply natural conditioner once yearly. Casati Milano atelier provides an 18-month warranty on all bespoke straps.
