Formula 1 CAZ101AH.BA0842— lug 22mm

The lug width is 22mm. This measurement defines the horizontal distance between the two attachment points where spring bars secure the strap. This is a critical specification: a strap must be purpose-built for 22mm to ensure correct fit, rotational stability, and aesthetic proportions appropriate to the 43mm case.

Alligator or shell cordovan are the reference choices for this chronograph. Alligator provides regular texture, subtle grain, and noble patina development over time; shell cordovan guarantees natural lustre, structural rigidity, and colour evolution through wear. Both respect the technical and sporty character of the ceramic and steel case.

The strap is secured with spring bars (small metal springs). Using a dedicated tool, you gently retract the springs from the case holes and extract the strap. To install a new one, insert the pins into the holes and release the springs so they click into position. The operation requires care and precision to avoid scratching the ceramic case.

Yes, provided it is constructed for a 22mm lug width. High-quality artisanal straps (alligator, shell cordovan, vegetable-tanned leather) are fully compatible and represent a superior alternative to original straps in terms of personalisation and longevity. Always verify the width before purchase.

A strap made from fine leather (alligator, shell cordovan with vegetable tanning) typically lasts 3–5 years under daily wear, depending on frequency and care. Leather fears standing water and prolonged dry heat; with light maintenance (quick drying, annual conditioning), durability extends. Artisanal straps offer progressive reinforcement, replacing stitching or portions of leather without discarding the entire strap.
