Strap for Navitimer Rattrapante Stainless Steel / Black / Croco / Pin

The lug width of the Breitling Navitimer AB031021/BF77/756P/A20BA.1 is 24mm. This measurement represents the distance between the two lateral pins of the case lugs that hold the strap, determining compatibility with any aftermarket strap. To verify, measure the distance between the case lugs: you will find exactly 24mm.

For the Navitimer AB031021/BF77/756P/A20BA.1, we recommend alligator in dark shades (mahogany or black) for formal-sportive wear, vegetable-tanned calf for everyday balance, NATO in stone grey for sporting environments, or FKM rubber for marine use. Your choice depends on predominant use and personal colour palette. Alligator enhances the watch's avionic heritage, whilst vegetable tanning develops a patina that ennobles with age.

The strap on the Navitimer AB031021/BF77/756P/A20BA.1 is changed using a spring bar removal tool. Locate the two lateral pins, one on each side, that hold the strap to the case lugs. Gently press the spring bar tool against one pin to release the strap, repeat on the other side. Insert the new 24mm strap by aligning the holes with the pins until you feel the locking click. Ensure the strap sits symmetrically against the case.

Yes, any strap with a 24mm lug width is compatible with the Breitling Navitimer AB031021/BF77/756P/A20BA.1. Lug width is universal: if your watch has lugs spaced 24mm apart, you can mount any 24mm strap, from nylon NATO to premium alligator or calf leather with steel deployant clasp. Choose based on your aesthetic preferences and intended use.

A quality leather strap (alligator or calf) worn daily has an average lifespan of 3-4 years before requiring replacement due to wear or cracks. Longevity depends on climate (humidity and heat accelerate ageing), frequency of use, and maintenance (keep leather dry, avoid prolonged contact with perspiration). A strap protected from moisture and worn occasionally can last 5-6 years. Vegetable tanning typically ages better than synthetic treatments, developing visual character whilst remaining functional.
