Strap for Navitimer B01 Chronograph 43 Stainless Steel / Blue / France

The Breitling Navitimer AB01383A1C1P1 features a lug width of 22mm. This is the internal measurement between the two lugs of the case, i.e. the width the strap attachment must match to ensure a correct fit without lateral play. It is advisable to verify the measurement with a digital calliper before purchasing an aftermarket strap.

For the Navitimer AB01383A1C1P1, the most suitable options are matte alligator leather in black or tobacco brown for a refined aesthetic, vegetable-tanned Tuscan calf leather for those seeking a natural patina over time, vulcanised rubber for sporting use, and ballistic nylon NATO straps to reference the model's aeronautical origins. The choice ultimately depends on context and personal aesthetic preference.

Strap replacement on the Navitimer AB01383A1C1P1 is carried out via standard spring bars linking the strap to the case lugs. Using a curved-tip spring bar tool or a professional lever, compress the spring bar inward and slide the strap free. Care must be taken to avoid scratching the case. For a first replacement, it is advisable to consult a watchmaker or the Casati Milano service.

Yes. Any strap with a 22mm attachment is compatible with the Navitimer AB01383A1C1P1, provided the overall length and taper are consistent with the case morphology. On milanostraps.it, a curated selection of handcrafted 22mm straps is available, specifically designed for chronographs of this calibre, with materials and finishes that respect the watch's quality level.

The lifespan of a leather strap depends on material quality and frequency of use. A high-quality alligator or vegetable-tanned calf leather strap, with regular conditioning using a nourishing cream, can last between three and five years with daily wear. Prolonged exposure to perspiration, water, and UV rays accelerates degradation. Milano Straps straps carry an 18-month warranty against manufacturing defects.
