Strap for Navitimer 01 43 Stainless Steel / Blue Edition / Croco / Pin

The lug width of the Breitling Navitimer AB012116/BE09/743P/A20BA.1 is 22mm. This measurement is taken with a digital calliper between the two case lugs and is the essential figure for selecting a compatible strap.

For the 43mm Navitimer with a black dial and gilt indices, a belly-cut alligator strap in cognac or dark grey offers the best balance between aeronautical character and refinement. Vegetable-tanned Tuscan calf leather is the most versatile everyday alternative, developing a distinctive patina over time.

Strap replacement requires a spring bar tool or a fine flat-blade screwdriver. The spring bars housed in the lugs are compressed at their tips and withdrawn laterally. Care must be taken to avoid scratching the stainless steel case. Alternatively, a watchmaker or specialist jeweller can perform the swap in a matter of minutes.

Yes. Any strap with a 22mm attachment width is technically compatible with this reference. Milano Straps offers a curated selection of handcrafted 22mm straps in premium leathers — alligator, calf, shell cordovan — with stitching and finishing proportioned to the 43mm case.

Longevity depends on leather type and usage. A vegetable-tanned calf strap worn daily typically lasts 18 to 30 months before showing evident wear at the fold. Alligator, owing to its scale structure and robust tanning, can last 3 to 5 years with routine care. Shell cordovan and dense leathers exceed average service life. Milano Straps provides an 18-month manufacturing warranty on all handcrafted straps.
