Strap for Navitimer 1 Chronograph GMT Stainless Steel / Black / Calf / Folding

The lug width of the Breitling Navitimer A24322121B2X2 is 24mm. This measurement refers to the distance between the two horizontal lugs of the case where the strap is inserted. It is important not to confuse this dimension with the case diameter (46mm) or other measurements of the watch. To verify correctly, remove the current strap and measure directly between the two attachment points using a digital calliper. All 24mm straps are compatible with this model, regardless of material.

The Breitling Navitimer A24322121B2X2, being a professional chronograph of 46mm, pairs ideally with robust and durable materials. Alligator leather in brown or dark blue emphasises the technical instrument aesthetic, whilst shell cordovan offers a deep lustre that refines over years. Vegetable-tanned calf leather is a versatile and breathable choice, perfect for daily wear. For sporty contexts, cotton NATO or Cordura nylon represent practical and authentic solutions. The choice depends on your lifestyle and predominant context of use.

The Breitling Navitimer A24322121B2X2 uses a simple and robust attachment system. To remove the current strap: position the watch on a soft surface with the dial facing downward, locate the lugs (the small pins protruding from the watch sides), use a dedicated tool (spring bar tool) to gently compress the pin and release it from the lug. Repeat on both sides. To insert the new strap, align the lugs with the gaps between the pins and reinsert the bars until they click into position. This process takes a few minutes and requires no particular technical skill.

Yes, any quality strap with a 24mm lug width is compatible with the Breitling Navitimer A24322121B2X2. Milano Straps offers artisanal straps in alligator, shell cordovan, calf leather and rubber, all crafted with 24mm lugs. Compatibility depends solely on lug width measurement, not on brand. A high-quality aftermarket strap can significantly improve the aesthetic experience and comfort compared to the original strap, especially if customised according to your preferences for material, colour and closure style.

The lifespan of a leather strap depends on the material, frequency of use and care applied. A high-quality alligator or shell cordovan strap, if worn daily, maintains excellent functionality and aesthetics for 5–7 years. Vegetable-tanned calf leather, being softer and more porous, has an average lifespan of 3–5 years with regular use. Longevity increases if the strap is exposed to challenging conditions (constant humidity, perspiration) less frequently and undergoes periodic maintenance (cleaning, hydration). Casati Milano offers an 18-month warranty on all bespoke straps, and these can be renewed at the atelier when the leather requires replacement.
