Strap for Pilot Automatic Chronograph Silver / Calf

The Formex Pilot 1100.1.8040.223 features a 22mm lug width. This dimension is determined by the 46.50mm case geometry and represents the standard specification for professional aviation instruments in this category. Accurate measurement is taken between the inner lugs using a digital calliper, ensuring precise fitment of any compatible strap.

The choice depends on intended use and personal aesthetic preference. For authentic aviation character, Tuscan vegetable-tanned leather in dark brown develops natural patina and vintage texture over time. For formal occasions, African alligator offers solid construction and directional grain. NATO straps in ballistic canvas provide tactical versatility for daily wear, whilst FKM rubber is ideal for extreme conditions or humid environments where leather loses elasticity.

The strap is replaced by removing the rivets or lug bars using a quality spring bar tool. Position the tool beneath the rivet, apply gentle inward pressure and lift with controlled motion. After extraction, insert the new 22mm strap ensuring the passant lugs align precisely with the case lugs. Avoid direct impacts against the titanium case during this operation.

Any strap manufactured for 22mm lugs is compatible with the Formex Pilot 1100.1.8040.223. International standardisation guarantees that leather, NATO, rubber and alligator from reputable suppliers will fit correctly. We recommend straps from recognised manufacturers for construction quality and material stability over time, always verifying the maker's technical specifications.

Lifespan depends on tanning method and usage intensity. A vegetable-tanned Tuscan strap, with regular maintenance (neutral grease application every 6–12 months), lasts 4–7 years. Alligator leather, being denser and more compact, reaches 7–10 years. Natural wear involves fibre thinning and potential fracture at maximum flex zones (lug attachment points). The patina developing in vegetable-tanned leather is a positive aesthetic characteristic.
